Answer:
ADE=59º
Step-by-step explanation:
4x+15+13x+7=90
17x+22=90
17x=68
x=4
angle B=angle ADE so we plug in x=4 into 13x+7
13(4)+7=59º
First, fill in the variables with the numbers given so that
2b-3c
will then become
2(4)-3(2)
next, you refer to the order of operations to simplify the problem down, the multiplication being the first doable operations in this problem.
8-6
and next operation being subtraction.
2
is the final answer
- 53.3 ° approxiametly
- In the given question:
- an angle which is three times of its compliment and less than 20°
- based on this statement , the equation formed
- 3x-20° = 180° (
- sum of supplement)
- 3x =180-20
- 3x= 160
- x=53.3
- complement angle is a sum of two angles which is equal to 90° , if two angles add up to form a right angle, then these angles are referred to as complementary angles
- supplement angle is sum of two angles which is equal to 180° , if two angles add up, to form a straight angle, then those angles are referred to as supplementary angles.
