Answer:
x = 7/6
Step-by-step explanation:
Solve for x:
35/74 (4/3 + 21/(5 x)) - 4/5 = 23/15
Bring 35/74 (4/3 + 21/(5 x)) - 4/5 together using the common denominator 1110 x:
(2205 - 188 x)/(1110 x) = 23/15
Cross multiply:
15 (2205 - 188 x) = 25530 x
Expand out terms of the left hand side:
33075 - 2820 x = 25530 x
Subtract 25530 x + 33075 from both sides:
-28350 x = -33075
Divide both sides by -28350:
Answer: x = 7/6
part A:
part B:
Measure of BC = 10.
This is an isosceles triangle because the 2 base angles are both 50 degrees.
So the 2 sloping sides AB and BC are also equal.
The diameter of a circle is twice the radius, so the statement is false.
