Answer:
X = 15
Step-by-step explanation:
We move all terms to the left:
<em>x+8+2x-(2x+13)=0</em>
We add all the numbers together, and all the variables:
<em>3x-(2x+13)+8=0</em>
We get rid of parentheses:
<em>3x-2x-13+8=0</em>
We add all the numbers together, and all the variables:
<em>x-5=0</em>
We move all terms containing x to the left, all other terms to the right:
<em>x=5</em>
Answer:
Step-by-step explanation:
g(x) = -4x + 5....find g(5)....sub in 5 for x
g(5) = -4(5) + 5
g(5) = -20 + 5
g(5) = -15 <===
Step-by-step explanation:
x+13⁰+10x+13⁰+2x-2⁰= 180⁰
13x= 180-24
13x=156
x = 12⁰
now angle Q = 10x+13⁰
= 10(12)+13= 120+13
= 133⁰
Answer: 67°
Step-by-step explanation:
Complementary angle refers to the angle that when added together will be equal to 90°.
Let the measurement of the angle's complement be x.
Therefore, the angles are x and 2x + 21. Since it's a complementary angle, therefore,
x + 2x + 21 = 90
3x + 21 = 90
3x = 90 - 21
3x = 69
x = 69°/3
x = 23°
Therefore, the angle will be:
= 2x + 21
= 2(23°) + 21°
= 46° + 21°
= 67°
The angle is 67°.
