Capitolo 2, Problema 29
Find the measure of each marked angle. See Example 2 supplementary angles with measures 10𝓍 + 7 and 7𝓍 + 3 degrees
Guida verificata passo dopo passo1
Recall that supplementary angles are two angles whose measures add up to 180 degrees. This means we can write the equation: \( (10\times x + 7) + (7\times x + 3) = 180 \).
Combine like terms on the left side of the equation: \( 10x + 7 + 7x + 3 = 180 \) becomes \( 17x + 10 = 180 \).
Isolate the variable term by subtracting 10 from both sides: \( 17x = 180 - 10 \) which simplifies to \( 17x = 170 \).
Solve for \( x \) by dividing both sides by 17: \( x = \frac{170}{17} \).
Once you find \( x \), substitute it back into each angle expression to find the measure of each angle: \( 10x + 7 \) and \( 7x + 3 \).
