Answer:
x+16+13= 90
x+29= 90
-29 -29
x= 61
But you can always check when you plug in the value of x
61+16+13= 90
Answer:
x = -4, y = 8.
Step-by-step explanation:
Question 16.
8x + y = -24 ........(A)
-3x - 2y = -4 ........(B)
Multiply (A) by 2:
16x + 2y = -48 Adding this to equation (B):
13x = -52
x = -4
Substituting this value of x in Equation (A):
8(-4) + y = -24
y = -24 + 32 = 8.
The measure of the angle ∠ABD is 64 degrees
<h3>How to determine the measure of the angle?</h3>
From the question, we have the following parameters:
Ray BA bisects ∠CBD
∠CBD = 5x + 18
∠ABC = 3x - 2
Because of the bisection, we have
∠ABC = ∠ABD
∠ABC * 2 = ∠CBD
Substitute the known values in the above equation, so, we have the following representation
(3x - 2) * 2 = 5x + 18
Open the brackets
6x - 4 = 5x + 18
Evaluate the like terms
x = 2
Recall that
∠ABC = ∠ABD
So, we have
∠ABD = 3x - 2
This gives
∠ABD = 3 x 22 - 2
Evaluate
∠ABD = 64
Hence, the angle is 64 degrees
