Answer:
52
Step-by-step explanation:
180-90-38=52
-x + 2y = 4
2y = x + 4
y = 1/2x + 2.....slope here is 1/2. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign. So the slope we need is -2 (see how I flipped the slope and changed the sign)
y = mx + b
slope(m) = -2
(-2,1)...x = -2 and y = 1
now we sub and solve for b, the y int
1 = -2(-2) + b
1 = 4 + b
1 - 4 = b
-3 = b
so ur perpendicular line is : y = -2x - 3
Answer:
<u>169 sq. cm.</u>
Step-by-step explanation:
<u>Surface Area</u>
- SA (base) + SA (2 sides) + SA (2 faces)
- 9 × 5 + 2 × 7 × 5 + 1/2 × 2 × 6 × 9
- 45 + 70 + 54
- <u>169 sq. cm.</u>
