Answer is 136. first we would find the area of the 2 triangles, formula is 1/2bh. which would give you 12, since there is 2 triangles would be 24. then you would find the area of the 3 rectangles around it which are 42, 35 and 35.
Answer:
238°
Step-by-step explanation:
In a cyclic quadrilateral, the pair of opposite angles add up to 180 degrees.
So, the angle "21x - 2" and the angle "38x + 5" add up to 180.
So, we can write an equation and solve for x first:
x = 3
Now, Arc FGH is DOUBLE of Angle A. Angle A is "38x + 5". We know x, so angle A is:
Angle A = 38x + 5 = 38(3) + 5 = 119
Thus, Arc FGH = 2 * 119 = 238°
A: what is y when x=-2
b: 65
