Answer:
a = 4.6
b = 4.2
Step-by-step explanation:
to find a, use cos:
⇒ cos = 
⇒ cos 30 = 
cos of 30 is 0.154
⇒ 0.154 =
multiply 13 on both sides:
⇒ 0.154 x 13 = x 13
⇒ 4.62 = a
round to the nearest tenth:
⇒ 4.62 = 4.6
⇒ a = 4.6
to find b, use tan:
⇒ tan = 
⇒ tan 60 = 
tan of 60 is 0.320
⇒ 0.320 =
multiply 13 on both sides:
⇒ 0.320 x 13 = x 13
⇒ 4.16 = b
round to the nearest tenth:
⇒ 4.16 = 4.2
⇒ b = 4.2
Answer:
The answer to your question is letter D
Step-by-step explanation:
Rational equation
Simplify
Cancel the denominators and expand
3x² + 1 + x² - x = 4x - 4 + 4
Simplify
4x² - x + 1 - 4x = 0
4x² - 5x + 1 = 0
Factor
4x² - 4x - 1x + 1 = 0
4x(x - 1) - 1(x - 1) = 0
(4x - 1)(x - 1) = 0
x₁ = 1/4 x₂ = 1
