Answer:
x = 20
Step-by-step explanation:
The interior angles of a regular octagon have measures of ...
180° -360°/8 = 135°
We want that equal to the given expression.
7x -5 = 135
7x = 140 . . . . add 5
x = 20 . . . . . divide by 7
The value of x is 20.
Step-by-step explanation:
the total angles in the triangle are 180°
so,
63° + 57° + ∠2 = 180°
120° + ∠2 = 180°
∠2 = 180° - 120°
∠2 = 60°

C
Step-by-step explanation:
Answer:
Since, three fourth of \(t\) is \(15\). Hence, the required equation is \(\frac{3t}{4}=15\)
Step-by-step explanation:
No, Yes, No, Yes
using the laws of exponents
