Angles α and β are the two acute angles in a right triangle. use the relationship between sine and cosine to find the value of β if β < α.

sin(2x + 2) = cos(3x + 8)
a) 16°
b) 34°
c) 56°
d) 74°

Step-by-step explanation:

we know that

in a right triangle

if sin A= cos B

then

angle A and angle B are complementary angles

so A+B=90

therefore

(7x-15)+(3x+5)=90> 10x-10=90> 10x=100> x=10°

so

7x-15> 7*10-15> 55°

3x+5> 3*10+5> 35°

we know that

β < α

therefore

the answer is

β =35°

α=55°

19.

step-by-step explanation:

you add the 9 in the tens column since it is a single digit and 9 plus zero is 9 so it is 19
