Answer:
- The angles do not share a special relationship.
Step-by-step explanation:
Angles 13 — 20 are right angles. Angle 12 is complementary to given angle 7, so is 90°-72° = 18°. Angle 10 is vertical with angle 12, so is also 18°.
There is no special relationship between right angle 14 and acute angle 10.
<span>2In4x= 2In8
ln(16x^2) = ln64
Multiply e by both sides.
16x^2 = 64
Divide both sides by 16
x^2 = 4
Take the square root of both sides.
x = 2</span>
To know if two fractions are proportionate, we need to cross multiply the fractions, if their cross products are equal, then they are proportionate, if not then they are not proportionate, however we can solve for the number that will make each fraction proportionate to the other.
12/21 = 15/24
cross multiply.
12*24 = 15*21
288 = 315 * not proportionate
because we use the 1st fraction as basis, we need to adjust the 2nd fraction to make it proportionate to the 1st fraction.
12/21 we can multiply the fraction by any number as long as we multiply the number to both numerator and denominator to keep the 2nd fraction in proportion to the first fraction.
