Answer:
B) 81°
Step-by-step explanation:
∡1 ≅ ∡5 because they are corresponding angles
∡5 ≅ ∡7 because they are vertical angles
therefore, ∡1 ≅ ∡7
since the angles are equal we can create the following equation:
3x + 18 = 2x + 39
x + 18 = 39
x = 21
∡7 = 2(21) + 39
∡7 = 42 + 39
∡7 = 81
Answer:
<h2><em><u>80</u></em><em><u>%</u></em>.</h2>
Step-by-step explanation:
<em><u>Since</u></em><em><u>,</u></em>
Any number if divided by hundred then that no. is known as a <em><u>percentage</u></em>.
<em><u>Here</u></em><em><u>,</u></em>
<em><u>80</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>divided</u></em><em><u> </u></em><em><u>by</u></em><em><u> </u></em><em><u>100</u></em><em><u> </u></em><em><u>i</u></em><em><u>. </u></em><em><u>e</u></em><em><u>.</u></em>
80 / 100
= <em><u>80% (Ans)</u></em>
