100 + 80 + 88 + 92 = 360
360 / 4 = 90
86 * 5 = 430
430 - 360 = 70
Answer = 70
100 + 80 + 88 + 92 + 70 = 430
430 / 5 = 86
Hope this helped☺☺
Answer:
700
Step-by-step explanation:
You multiply the two numbers together
20x35=700
700/20=35
We know that
If a tangent segment and a secant segment are drawn to a <span>circle </span><span>from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment
</span>so
AB²=BD*BC
BD=12
BC=12+15----> BC=27
AB²=12*27----> 324
AB=√324----> AB=18
the answer is
AB=18 units
