Answer:
Step-by-step explanation:
The angle marks show that ΔRST is isosceles, so RT = RS. They also show ΔRTU to be equilateral, so UT = RT.
UT = RS
x -5 = 15
x = 20 . . . . . . add 5
__
ΔRTU is equilateral, so ∠RTU is 60°. The angle marked 3y° is complementary to that.
3y = 30
y = 10 . . . . . divide by 3
Answer:
d = 1
Step-by-step explanation:
The equation given is:
0.5(7d + 4) = 7 - 1.5d
Expand the bracket:
3.5d + 2 = 7 - 1.5d
Collect like terms:
3.5d + 1.5d = 7 - 2
5d = 5
d = 5 / 5 = 1
Answer:
