Use the law of Cosines where
angle A = 14+22=36 degrees
side b = 6 times 7
side c = 6 times 19
So you have a triangle with 2 legs of 42 and 114 with angle A = 36 degrees between them.
The law of Cosines is then
a^2 = 42^2 + 114^2 - 2(42)(114)Cosine(36)
Solve and take the square root.
= 7012.85 taking the square root of it
= 83.74 km apart
Answer:
<h2>-3 ; 3</h2>
Step-by-step explanation:
4x² - 36 = 0 ⇌ (2x)² - 6² = 0 ⇌ (2x - 6)(2x + 6) = 0 ⇌ 2x - 6 = 0 or 2x + 6 = 0
⇌ x = 3 or x = -3
<u>Answer:</u>
It would be 81

E hope this helps but hi my name is hailey
Answer:
Explanation:
The exponent of 0.52 is not 9 but q. Thus, you need so solve the equattion to find the value of the exponent, q.
To solve exponential equations with different bases, you must use logarithms, which is the inverse function of exponentiation:
