That would be true because the adjacent side to B is 4 and the hypotenuse is 5 and the formula for cos b is adjacent/hypotenuse
Hope this helps!
Answer:
41 21/25
Step-by-step explanation:
38 1/25 + 3 4/5 = 41 21/25
Answer:
90 square cm.
Step-by-step explanation:
For similar figures, the length of corresponding sides are proportional.
So we can write 4k = 6 where k is the proportionality constant.
<u>Note: </u>In terms of area, the scale factor would be k^2 and in terms of volume, it would be k^3y
Solving 4k = 6, we see that k = 6/4 or 3/2
We need area, so we <u><em>multiply area of ABC by k^2 to get area of PQR.</em></u>

Area of PQR = 90 cm^2
Step-by-step explanation:
(-3,-2)
that is the translation matrix for this question
