Answer:
um wat?
Step-by-step explanation:
Answer:
25 degrees
Step-by-step explanation:
85 +x-10 + 2x=180
85-10+3x=180
75+3x=180
3x=105
x=35
35-10=25
Answer:
42
Step-by-step explanation:
It's just a distribution property where the given value of each variables (a, b, c, d) are being distributed to the given equation:
7a2-3ac+d2
7(2)(2) - 3(2)(-3) + (-2)(2)
28 + 18 - 4 = 42
These 2 tangents are equal in length so:-
x + 10 = 2x - 1
10 + 1 = 2x - x
x = 11
and GH = 10+11 = 21
