It is the other way around. Angle A = 75° and angle B = 105°.

105° and A are what they call allied/co-interior angles. They must add up to 180°. A= 180°-105° = 75°.

75° and B must also add up to 180°. 180°-75° = 105°.

Answer:

b=320; slope=-30

Step-by-step explanation:

if you look along the y-axis find the spot that the line intercepts and then that's b

now for the slope

find two points on the line, i chose(8 , 120) and (4 , 240)  

use the slope formula: y2-y1 over x2-x1

240-120=120 and 4-8= -4

so the slope is 120/-4 and that can be simplified to 30/-1 or -30

What is -2(5x + 1 ) + 3(3x - 9 )
ioda

Answer:

-x - 29

Step-by-step explanation:

-2(5x + 1) + 3(3x - 9) =                 First, distribute the numbers in the parenthesis

   -10x - 2 + 9x - 27 =                  Then, combine like terms

(-10x + 9x) + (-2 - 27)=                 Next, distribute the digits

                        -x - 29

What percent of 55 is 13??
polet [3.4K]
What percent of 55 is 13

percent means parts out of 100
x%=x/100

'of' means multiply

what percent of 55 is 13 means
x/100 times 55=13
times both sides by 100
55x=1300
divide both sides by 55
x=23.63636363636363
answer is 23.63%
