Based on the given equation above, get the value of x first so that this value can be substituted to the second equation. Value of x can be obtained by taking the arc sin of 7/11 which gives an answer of 39.52 degrees. Substituting this value to the second equation cos (90-39.52) gives an answer equals to 7/11
Answer:
4
Step-by-step explanation:
6(6+x) = 5(5+x+3)
36+6x = 25+5x+15
6x-5x=40-36
x=4
All you have to do is subtract 38 from 45 to get 7 as your answer.
Answer:

Step-by-step explanation:
∠E = 1/2 (mCD - mAB)
<u>Where mCD = 110° and mAB = 30°</u>
∠E = 1/2 (110° - 30°)
∠E = 1/2 (80°)
∠E = 40°
