Answer:
<h2>32° and 58°</h2>
-by-step explanation:
Let x be the measure of angle 1
and y be the measure of angle 2
The Two angles are complementary
means
x + y = 90
their difference is 26 degrees
means
x - y = 26
x + y = 90 (1)
x - y = 26 (2)
(1) - (2) ⇒2y = 64 ⇒ y =32°
therefore x = y + 26 = 58°

Answer:
A=32
B=3
C=7
Step-by-step explanation:
Caitlyn surveyed 100 students to find out their favorite class. There were 29 students who enjoyed biology and 35 students who enjoyed English. There were 12 students who did not enjoy Biology, English, or Math.
29 like Biology so to find B you subtract. 29-6-5=3
35 like English so to find C 35-3-5-20=7
Total of 100 students subtract what you know to find A.
100-15-6-5-3-7-20-12=32
