Answer:
B *second one down.
Step-by-step explanation:
EF = 1/2(AB + CD)
x+5 = 1/2 (2x + 2 + 2x+4) Combine the like terms on the right.
x+5 = 1/2 (4x + 6) Remove the brackets.
x+5 = 1/2*4x + 1/2*6
x+5 = 2x + 3 Subtract x from both sides
5 = 2x-x + 3
5 = x + 3 Subtract 3 from both sides
5-3 = x
x = 2
EF = x + 5
EF = 2 + 5
EF = 7
The answer is B

Answer:
Step-by-step explanation:
<u>We know that:</u>
- sin 30° = 1/2, therefore arcsin (1/2) = 30°
- tan 45° = 1, therefore arctan (1) = 45°
<u>So the value of the expression is:</u>
- arcsin (1/2) + arctan (1) = 30° + 45° = 75°
