Answer:
135°
Step-by-step explanation:
a supplementary angle is equal to 180°. since you already have the measure of ZA, all you need to do is subtract 45°, the measure of ZA, from 180°, the total measure of a supplementary angle, in order to figure out the measure of ZB.
180 - 45 = 135, therefore the measure of ZB = 135°.
Answer:
Gerard's blue section is larger.
Step-by-step explanation:
Eve divided her half into 6 equal sections and painted one section blue.
So, the blue-painted part will be of size 
part of the whole poster.
Again, Gerard divided her half into 5 equal sections and painted one section blue.
So, the blue-painted part will be of size 
part of the whole poster.
Now, since 12 > 10, so, 
Therefore, Gerard's blue section is larger. (Answer)
Answer:
B
Step-by-step explanation:
use the slope formula to find the slope. y2-y1/x2-x1. 3-(-6)/-4-2 which is 9/-6 (subtracting a negative number is the same as adding a positive) which can be simplified to -3/2 which is the slope. the intercept is the point where y is at x=0, we already know at y=3 x is -4 from the second point, so the y intercept has to be -3. which can be proven by replacing the x and y with a point 3 = -3/2(-4) - 3. put -3/2 times 4 into a calculator and you get 6, 6-3 is 3 which makes the statement true.
