- For problem 1:
- Explanation:
- Step 1: Use angle - addition property
- We know that \(m\angle KST=m\angle RSK + m\angle RST\). Given \(m\angle KST = 160^{\circ}\), \(m\angle RST=37x - 5\), and \(m\angle RSK = 5x - 5\). So, we can write the equation \(160=(5x - 5)+(37x - 5)\).
- Step 2: Simplify the right - hand side of the equation
- Combine like terms: \((5x - 5)+(37x - 5)=5x+37x-5 - 5=42x-10\). So the equation becomes \(160 = 42x-10\).
- Step 3: Solve for \(x\)
- Add 10 to both sides of the equation: \(160 + 10=42x-10 + 10\), which gives \(170 = 42x\). Then divide both sides by 42: \(x=\frac{170}{42}=\frac{85}{21}\approx4.05\).
- For problem 2:
- Explanation:
- Step 1: Use angle - addition property
- We know that \(m\angle STU=m\angle STG + m\angle GTU\). Given \(m\angle STG=x + 32\), \(m\angle GTU=x + 35\), and \(m\angle STU = 61^{\circ}\). So, we can write the equation \(61=(x + 32)+(x + 35)\).
- Step 2: Simplify the right - hand side of the equation
- Combine like terms: \((x + 32)+(x + 35)=x+x+32 + 35=2x+67\). So the equation becomes \(61 = 2x+67\).
- Step 3: Solve for \(x\)
- Subtract 67 from both sides: \(61-67=2x+67 - 67\), which gives \(-6 = 2x\). Then divide both sides by 2: \(x=-3\).
- For problem 3:
- Explanation:
- Step 1: Use angle - addition property
- We know that \(m\angle DEF=m\angle DEG + m\angle GEF\). Given \(m\angle DEG = 17x-3\), \(m\angle GEF = 114^{\circ}\), and \(m\angle DEF=44x + 3\). So, we can write the equation \(44x + 3=(17x-3)+114\).
- Step 2: Simplify the right - hand side of the equation
- Combine like terms: \((17x-3)+114=17x+111\). So the equation becomes \(44x + 3=17x+111\).
- Step 3: Solve for \(x\)
- Subtract \(17x\) from both sides: \(44x-17x + 3=17x-17x+111\), which gives \(27x+3 = 111\). Then subtract 3 from both sides: \(27x+3 - 3=111 - 3\), so \(27x = 108\). Divide both sides by 27: \(x = 4\).
We will solve the remaining problems in a similar fashion. For example, for problems involving line - segment lengths, if we have a line - segment \(AB\) with a point \(C\) on it such that \(AB=AC + CB\), we can set up an equation based on the given expressions for \(AB\), \(AC\), and \(CB\) and solve for \(x\).
Let's take problem 4:
- If we assume that the length of the whole line - segment is the sum of the lengths of its sub - segments. Let the whole line - segment be \(TV\) and \(TV=TS+SU+UV\). But since only \(TS=x + 10\) and \(SU = 2x+18\) are given (assuming \(UV\) is not relevant for the equation setup based on the information available), we need more information to solve this problem completely.
For a general line - segment problem, say we have a line - segment with endpoints \(M\) and \(K\) and a point \(L\) on it such that \(MK=ML+LK\). If \(MK = 17 + x\), \(ML=2x + 16\), and \(LK = 8\), then:
- Explanation:
- Step 1: Set up the equation
- \(17 + x=(2x + 16)+8\).
- Step 2: Simplify the right - hand side
- \((2x + 16)+8=2x+24\). So the equation is \(17 + x=2x+24\).
- Step 3: Solve for \(x\)
- Subtract \(x\) from both sides: \(17 + x-x=2x-x+24\), which gives \(17=x + 24\). Then subtract 24 from both sides: \(17-24=x\), so \(x=-7\).
We can continue this process for all the remaining line - segment and angle - related problems.
