Answer:
x=7
Step-by-step explanation:
This is a right triangle, we can use sin , cos, and tan
tan theta = opposite side/ adjacent
tan 45 = 7/x
Multiply each side by x
x tan 45 = 7/x *x
x tan 45 =7
Divide each side by 45
x tan 45 / tan 45 = 7/ tan 45
x = 7 / tan 45
x =7
Answer:
part a. A
part b. x + 6
part c. (4x – 1)(3x + 6)
Step-by-step explanation:
width + x + x = 3x + 6
width = 3x + 6 – x – x /answer for part a/
width = x + 6 /answer for part b/
Area = (length)(width) = (4x – 1)(3x +6) /part c/
Answer:
76 degrees.
Step-by-step explanation:
Let as consider O is the center of the circle . So from the figure it is clear that
By central angle theorem, central angle subtended by an arc is twice of inscribed angle of the same arc.
We know that,
and angle BOD is the central angle subtended by arc BD.
Now,
Therefore, the measure of arc BC is 76 degrees.
