Answer:
85°
Step-by-step explanation:
Since you know that the overall angle measure for the whole shape is 540°, you can subtract the known angles measures to find the right one.
540-90
450-90
360-115
245-160
85
Answer:
x = 9
∠B = 7 x 9 - 1 = 62°
∠BCD = 120°
Step-by-step explanation:
exterior angle of a triangle is equal to the sum of two opposite interior angles
∠BCD = ∠CBA + ∠BAC
10x + 30 = (7x - 1) + (58)
10x + 30 = 7x + 57
3x = 27
x = 9
∠B = 7 x 9 - 1 = 62
∠BCD = 10 x 9 + 30 = 120
Here's an answer, with some big 'IF's attached. We can't be
sure of anything, because you never shared the picture of it
that was 'shown above'.
The area of a trapezoid is (1/2) (height) (base-1 + base-2).
Now, <u>IF</u> 'x' is one of the bases, and <u>IF</u> 'y' is the other one,
and <u>IF</u> 'h' is the height of the trapezoid, then
Area = (1/2) (6) (14 + 8)
= (3) (22) = <em>66 square units</em>.
But if any of them is not, then it isn't.
you mean : 5/8x + 1/16x = 5/16 +x
<=> 10/16x +1/16x = (5 +16x)/16
(16x # 0)
<=> 11/16x = x(5+16x)/(16x)
<=>11 = x(5+16x)
<=> 11 = 16x^2 + 5x
<=> x =-1 or x =11/16
