Answer: B
Step-by-step explanation: I think if it is wrong i am so so so so so so sorry but i am 79.99999% positive
0.89 x 0.98 = 0.8722, so you answer is 0.8722
Answer:
a = 82
b = 130
c = 118
Step-by-step explanation:
A quadrilateral is inscribed in a circle. So, it is a cyclic quadrilateral.
Opposite angles of a cyclic quadrilateral are supplementary.
Therefore,
a° + 98° = 180°
a° = 180° - 98°
a° = 82°
a = 82
By inscribed angle theorem:
a° = 1/2(b° + 34°)
82° * 2 = b° + 34°
164° - 34° = b°
b° = 130°
b = 130
Again by inscribed angle theorem:
76° = 1/2(c° + 34°)
76° *2 = c° + 34°
152° - 34° = c°
c° = 118°
c = 118
Answer:
250 degrees
Step-by-step explanation:
The arc intercepted by the angle formed by a secant and a tangent is twice the measure of the angle. See the attached image. The intercepted arc measures 110 degrees.
x is the measure of the rest of the circle, so it is 360 - 110 = 250 degrees.
Answer:
Step-by-step explanation:
cos A = 36/45 = 4/5 answer is C
sin A = 27/45= 3/5
tan A = 27/36= 3/4
sec A = 45/36= 5/4
csc A = 45/27= 5/3
cot A = 36/27= 4/3
