Since y = 3x+5 and y = 3x+8 are parallel (same slope), then the 2 lines wqill never intersect, hence there is no solution
Would it be easier if you rounded 75 to 80?
Or........
We already know 12 x 12 =144. So all you could do isis add 12 to 144 to get your complete answer. Which is:
12 x 13 = 156
m∠ZAB + m∠CAB = 180° by the angle addition postulate
m∠CAB + m∠ACB + m∠CBA = 180° because of the triangle angle sum theorem
m∠ZAB = m∠ACB + m∠CBA using the subtraction property
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
m∠ZAB + m∠CAB = 180° by the angle addition postulate
m∠CAB + m∠ACB + m∠CBA = 180° because of the triangle angle sum theorem
m∠ZAB = m∠ACB + m∠CBA using the subtraction property
