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: 0.64
Step-by-step explanation:
Given : The heights of women aged 20 – 29 in the United States are approximately Normal with
inches and
inches.
Let x denotes the height of women.
Since 1 feet = 12 inches
5.5 feet =
inches
Then, the z-score corresponds to x=66 inches will be :-

Hence, the z ‑score for a woman 5.5 feet tall = 0.64
