Answer:
<u><em>Measure of angle A is 27 7/9 degrees.</em></u>
Step-by-step explanation:
Lets call measure of angle A is <em><u>X-10</u></em>
Lets call measure of angle B is X
Lets call measure of angle D is 2.5X+20
We know that the sum of triangles add up to 180 degrees
X+X-10+2.5X+20=180
X=37 7/9
So measure of angle A is 27 7/9 degrees.
I hope this is right. :)
Hey there!
<u>Solve </u><u>the </u><u>equation</u><u>:</u>
c = 7 ✅
2c + 3 = 3c - 4
<em>></em><em>></em><em> </em><em>Subtract </em><em>3</em><em> </em><em>from </em><em>both </em><em>sides </em><em>:</em>
<em> </em>
2c + 3 - 3 = 3c - 4 - 3
2c = 3c - 7
<em>></em><em>></em><em> </em><em>Substrat </em><em>3</em><em>c</em><em> </em><em>from </em><em>both </em><em>sides </em><em>:</em>
2c - 3c = 3c - 7 - 3c
-c = -7
<em>></em><em>></em><em> </em><em>Divide</em><em> </em><em>each </em><em>side </em><em>by </em><em>-</em><em>1</em><em> </em><em>:</em>
-c / -1 = -7 / -1
c = 7
2c + 3 ⇔ 2(7) + 3 ⇔ 14 + 3 ⇔ 17
3c - 4 ⇔ 3(7) - 4 ⇔ 21 - 4 ⇔ 17
Therefore, your answer is c = 7 .
