Answer:
x = 5/3
Step-by-step explanation:
Solve for x:
7 x - 15 = -2 x
Add 2 x to both sides:
7 x + 2 x - 15 = 2 x - 2 x
2 x - 2 x = 0:
7 x + 2 x - 15 = 0
7 x + 2 x = 9 x:
9 x - 15 = 0
Add 15 to both sides:
9 x + (15 - 15) = 15
15 - 15 = 0:
9 x = 15
Divide both sides of 9 x = 15 by 9:
(9 x)/9 = 15/9
9/9 = 1:
x = 15/9
The gcd of 15 and 9 is 3, so 15/9 = (3×5)/(3×3) = 3/3×5/3 = 5/3:
Answer: x = 5/3
Answer:
Step-by-step explanation:
- Let the smaller angle be x
- Then the other angle is 5x
<u>Sum of acute angles equals to 90°</u>
- x + 5x = 90°
- 6x = 90°
- x = 90°/6
- x = 15°
The smallest angle is 15°
Answer:
Q + S = 360 - 55 - 45 = 260
Q = S
=> Q = 260/2 = 130
C is correct
