Answer: x = 12
Step-by-step explanation:
We know that the whole angle is 90°. Therefore, we can set up our equation like this:
90 = 50 + 3x + 4
Lets combine like terms:
90 = 54 + 3x
Now, let’s isolate the variable. To do this, we have to move 54 to the other side, making it negative.
90 - 54 = 3x
36 = 3x
Now, you divide, the leave the variable by itself.
=
Therefore, x = 12.
Answer:
Step-by-step explanation:
Given the right angled triangle, ∆BCD, you are required to find the measure of angle C.
Apply the trigonometric ratio formula to find m < C.
Adjacent side = 7
Hypotenuse = 8
Trigonometric ratio formula to apply would be:
