Solve using substitution.
4a=3b+3
a=b-1

Answers

Answer 1

Answer: 4(b-1)=3b+3
4b-4=3b+3 -- subtract 3b from both sides
b-4=3 -- add 4 to both sides

b=7
Substitute b into equation 2
a=b-1
a=7-1

a=6

Verify:
4(6)=3(7)+3
24=21+3
24=24 -- True.

Answer 2

Answer: 4a=3b+3
Put a=b-1 in the above equation
4(b-1) = 3b+3
open the brackets
4b - 4 = 3b + 3
collect B-terms together on one side
4b - 3b = 3+4
b = 7

What is mean by Angle?

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

We have to given that;

⇒ cos 53 degree

Hence, We can change it into sine as;

⇒ cos 53 degree

⇒ sin (90 - 53)

⇒ sin 37 degree

Thus, The value of cos 53 degrees in terms of sine is,

⇒ sin 37 degree
