Answer:
Step-by-step explanation:
we know that the triangle to the center is an isosceles, so the two angle on the circle of that triangle are the same. both 41, so 41*2 =82
all the way around that isosceles triangle is 180 so
180-82 = 98
the angle at O is 98°
the arc BC spans 98°
angle 'a' is 1/2(98°)
a = 49°
Answer:
90m+145
Step-by-step explanation:
80 + 50m + 65 + 40m
90m+145
Answer:11.8
Step-by-step explanation:
(9x+5)=112
9x=107
X=11.8
Hope I’m right
Sorry if i’m wrong or too late but i think you would have to divide 7 by those numbers
Because tan theta > 0 and cos theta is negative this angle is in the third quadrant.
angle whose cos is 2/5 is 66.42 degrees
The required angle is 180 + 66.42 = 246.42 degrees answer.
