Answer:
(a) 3x+28+5x+52+2x-10=180 (∠ sum of Δ)
10x+70=180
10x=110
x=11
(b) ∠C = 2x-10
= 2(11)-10
= 12°
Answer:
You can find the diagonal of a rectangle if you have the width and the height. The diagonal equals the square root of the width squared plus the height squared.
92+72−−−−−−√=11.4

Answer:
Center (-13,11) , radius 3
Step-by-step explanation:
The given circle has equation

We compare this to the general equation.

where (-a,-b) is the center.
This implies that;
2a=26

2b=-22
b=-11
The center is therefore (-13,11)
The radius is given by



The radius is 3
