Answer:
x = 8
Step-by-step explanation:
40 + 6x + 2 = 90 {Complementary angles}
Combine like terms
40+ 2 + 6x = 90
42 +6x = 90 {Subtract 42 form both sides}
6x = 90 - 42
6x = 48 {divide both sides by 6}
6x/6 = 48/6
x = 8
Answer:
B= -40
Step-by-step explanation:
So a right triangle has to = 180
So we write the given, which 124+99
we are trying to get 180 so lets subtract that by the equation, 180-124+99
180-(124+99)
12+99=223
180-223
=-43
But in your case it has to be rounded to the nearest tenth
So the answer is -40
Answer:
-66/7
Step-by-step explanation:
1/3x-11=3/2x
2/6x-11=9/6x
7/6x=-11
x=-66/7
Answer:
612
Step-by-step explanation:
To find this answer, you can invert the equation:
452.88 = 0.74x
x = 452.88 / 0.74
x = 612
