Step 1: Calculate. We calculate the square root of 87 to be: √87 = 9.32737905308882.
Step 2: Reduce. 9.32.
Step 3: Round. Round 9.32 so you only have one digit after the decimal point to get the answer: 9.3.
The tangent at A is perpendicular to OA, so has a slope that is the negative reciprocal of that of the radius: -1/2.5 = -2/5.
78 / 0.26 = 300 so the answer is 300
Answer:
B is 45 A is 135

45 x 3 = 135
135 is three times as large as 45
135 and 45 are supplementary angles
