Because the triangle is equilateral we know that z=60, therefore:

$60=\frac{1}{3}x-7$
$67=\frac{x}{3}$
$67 \times 3 = x$
$x=201$ <span />

I need help with this one because I got my answers wrong

cluponka [151]

40+60+y=180
y=180-100
y=80

A triangle is 180° so you add all the numbers available in the trianle and minus it with 180 to see what is left from the 180 and that will be the inner angle answer

X=180-80=100

A straight line is also 180° so if u minused one side which in our case is 80 u will get the rest which is the outer angle

Question

Virty [35]

Answer:

m∠1 = 107 degrees

m∠2 = 73 degrees

Step-by-step explanation:

1. ∠1 and the angle with 107 degrees are corresponding angles, which are located in the same relative position. They're congruent in measures, so m∠1 = 107 degrees.

2. ∠1 and ∠2 are a linear pair, meaning their angle measures add up to 180 degrees. Given m∠1 = 107 degrees, we just have to subtract 107 from 180 to get m∠2.
