Answer:
DE=145
Step-by-step explanation:
Both circles are congruent and so are the triangles, because of the radius. So mDE is also 145
Answer:
see explanation
Step-by-step explanation:
(a)
The angles are vertical and congruent, that is
x - 10 = 125 ( add 10 to both sides )
x = 135
-------------------------------------------------
(b)
Supplementary angles sum to 180°
The angles are in the ratio 2 : 3 = 2x : 3x ( x is a multiplier ), then
2x + 3x = 180
5x = 180 ( divide both sides by 5 )
x = 36
thus
2x = 2 × 36 = 72
3x = 3 × 36 = 108
Then the 2 angles are 72° and 108°
Answer:
748 trees PLEASE GIVE BRAINLIEST
Step-by-step explanation:
b + 2c + 3jb + 2c + 3j =
88 + 2(33) + 3(44)(88) + 2(33) + 3(44) =
88 + 66 + 396 + 66 + 132 = 748 trees
