Answer:
C. 85 degrees
Step-by-step explanation:
(set the equations equal to each other):
6x-25 = 4x+15
(solve for x):
2x = 40
x = 20
(plug in x back into the equation):
6(20)-25 = 120-25 = 95
(subtract your value from 180 degrees (180 degrees is a line)):
180-95 = 85 degrees
Answer:
117in²
Step-by-step explanation:
9*13=117
To do it mentally means to do it in your head
first do 7 * 3 = 21 in your head
than do 7 * 0.8 = 5.6 ( this might be hard to do in your head but you know 7*8 = 56 so add a decimal since it is 0.8 not 8 )
Add : 21 + 5.6 = 26.6
Final Answer : 26.6
Answer:
(x-1)(5x^2-7)
Step-by-step explanation:
we know that
The measure of the interior angle is the half-sum of the arcs comprising it and its opposite.
so
<u>Find the measure of the angle LAM</u>
m∠LAM is equal to
<u>Find the measure of the angle MAJ</u>
we know that
m∠LAM+m∠MAJ=° ------> by supplementary angles
m∠MAJ=
m∠MAJ=°
therefore
<u>the answer is</u>
The measure of the angle MAJ is
