∠A and ∠B are supplementary such that
1 answer:
Answer:
The equation is;
(2x-2) + (4x + 2) = 180
x = 30
m∠A = 58
Step-by-step explanation:
Mathematically, when two angles are supplementary, the values of both angles add up to be 180
From
what we have here;
(2x -2) + (4x + 2) = 180
2x -2 + 4x + 2 = 180
6x = 180
x = 180/6
x = 30
Recall;
The measure of angle A is as follows;
2x -2 = 2(30) - 2 = 60-2 = 58

The conversion is
x = magnitude × cos(angle)
y = magnitude × sin(angle)
or
(x, y) = 120.2(cos(119°), sin(119°)) ≈ (-58.27, 105.13)

A suitable graphing calculator handles this easily.
Answer:
G. 
Step-by-step explanation:
The factors of 56: 1; 2; 4; 7; 8; 14; 28; 56
The factors of 84: 1; 2; 3; 4; 6; 14; 28; 42; 84
GCF(56; 84) = 28
Answer:

Step-by-step explanation:
AB = BE = 5
BD = BE + ED = 5 + 3 = 8
BC = 8
BD = BC
CD = 5 which is not equal to 8.
Triangle BCD has exactly 2 congruent sides.
Answer: Triangle BCD is isosceles.
