It’s an equilateral triangle so all of the triangle angles add up to 180 and since it’s equilateral each angle is 60 degrees. Setting 8y-4=60, 8y=64, thus y=8 degrees.
Answer:
60
Step-by-step explanation:
1. Substitute
8 (10) - 20
2. Multiply
80 - 20
3. Subtract
60
Answer:
For part A
10.08x=y
Step-by-step explanation:
252/25=10.08
x=number of hours=25
y=how much earned=252
10.08(25)=252
WXY = XYW ( = 41 ) ⇒ XYW is a isosceles triangle
⇒ XW = YW
⇒ 54 = 6x + 6
⇒ 6( x + 1 ) = 54
⇒ x + 1 = 9
⇒ x = 8
ok done. Thank to me :>
