The statements that are true are:
A. m<AGB = 19°
D. <BGD is a right angle
<h3>What is a Right Angle?</h3>
A right angle is an angle that measures 90 degrees.
Given the diagram, where:
m<AGC = 38°,
m<CGD = 71°,
m<FGC = 147°
We have the following measures:
1/2(m<AGC) = m<AGB
1/2(38) = 19°
m<CGD + m<AGC = m<BGD
Substitute
71 + 19 = m<BGD
90 = m<BGD
m<BGD = 90° [this is a right angle].
Therefore, the statements that are true are:
A. m<AGB = 19°
D. <BGD is a right angle

Answer:
D: 12
Step-by-step explanation:
The entire segment KI is composed of the segments KJ and JI. So:
We know that KI is 15.
KJ is (2x-15) and JI is (2x-6). Substitute:
Solve for x. Combine like terms:
Add 21 to both sides:
Hence, the value of x is:
We know that JI is 2x-6.
We will substitute 9 for x to find JI. So:
Hence, our answer is D.
Write
, and recall that for a differentiable function
, the derivative at a point
is given by
which would suggest that for this limit,
and
. We have
, and so the value of the limit would be
.
You first need to get x on one side, so you first subtract 35 from both sides, and you get
-4x < 2
then you divide by -4 on both sides, so you get
x < -0.5
