How do I solve this?

x=60° , y=30° , z= 75°

Step-by-step explanation:

note...an equilateral triangle has the same angles all equal to 60°. so based on this x is 60°

the angle next to y is on a straight line therefore

60 +y =90

y=90-60

y=30°

the triangle with the y and z angles is an isosceles triangle...so the base angles must be equal

z+z+30=180

2z+30=180

2z=180-30

2z=150

z=75°

d

step-by-step explanation:

choose (5, 1.5) and (-1.5,-3.5)

step-by-step explanation:

5 - 1.5 =3.5

-1.5 - (-3.5) = 2

3.5 + 2 =5.5

hope this !
