as in right angle one has to be 90 degree others sum should be equal to 90
so if 3x+6 and 2x-1 are smaller angle their sum should add up to 90
3x+6+2x-1=90
x=17
answer is 2x-1 is smallest=33°
Answer:
y=85°
p=100°

Answer:
3. Option 2 (Perpendicular)
4. Option 3 (neither)
Step-by-step explanation:
3.
m1 = -7/8
Second equation: -8x + 7y = -21
7y = 8x - 21 y = (8/7)x - 3
m2 = 8/7
m1 & m2 are not equal, so not parallel
Since m1×m2 = (-7/8)(8/7) = -1,
They are Perpendicular
4.
m1 = -1/4
Second equation: -2x + 8y = 6
8y = 2x + 6 y = (1/4)x + 3/4
m2 = 1/4
m1 & m2 are not equal, so not parallel
Since m1×m2 = (-1/4)(1/4) = -1/16, not -1. They are not Perpendicular either. So, neither
Answer:
Step-by-step explanation:
The surface area of a sphere (which the earth is considered to be) = 4 pi r^2
pi = 3.14
r = 6340
Area = 4 * 3.14 * 6340 * 6340 = 504856736 square km.
You should either round this to 505,000,000 or express a value in scientific notation.
5.05 * 10^8
Answer:
x = - 1.10 and x = 1.10
Step-by-step explanation:
Given
25x² - 30 = 0 ( add 30 to both sides )
25x² = 30 ( divide both sides by 25 )
x² = 
( take the square root of both sides )
x = ± 
x = - 1.10 and x = 1.10 ( to the nearest hundredth )
