Answer:
34
Step-by-step explanation:
(180-x)-2(90-x)= 53
Remember that complimentary angles add to 90 and supplementary angles add to 180.
180-x-180+2x=53
x=53
Final answer: The angle is 53 degrees.
Answer:
x = 348
Step-by-step explanation:
From the given we can tell it a supplementary angle.
<u>Don't know what supplementary angle is?</u>
<em>Supplementary angle are angles that :</em>
<em>Equal 180 °</em>
<em />
<u><em>Solve: </em></u>
<em>Since,</em>
<em>∠ABD is (0.18x+54)° </em>
<em>∠CBD is (0.07x+39)°</em>
<em />
<em>Thus,</em>
<em>(0.18x+54) + 0.07x + 39 = 180</em>
<em>Group likes terms:</em>
<em>0.25x + 54 + 39 = 180</em>
<em>0.25 + 93 = 180</em>
<em>Subtract 93 from both sides</em>
<em>0.25x = 87</em>
<em>x = 348</em>
<em />
<em>Check Answer:</em>
<em>0.18(348) + 54 + 0.07(348) + 39 </em>
<em>= 180</em>
