Answer:
AB = 10.83 cm
Step-by-step explanation:
From ΔABC,
m∠B = 90°
By applying sine rule in the given triangle,
sinθ =
sin(37°) =
AB = AC(sin37°)
AB = 18×(0.060182)
= 10.833
≈ 10.83 cm
Therefore, AB = 10.83 cm is the answer.
Answer: X = 11/5
Step-by-step explanation: Put it in standard form first!!
simplify -2 + 4x = 9 - x
regroup items 4x - 2 = 9 - x
Add two on both sides 4x = 9 - x + 2
simplify 9 - x + 2 to 11 - x
4x = 11 - x
Add x to both sides 4x + x = 11
Simplify 4x + x to 5x
5x = 11
divide both sides by 5
x = 11/5
2(5)+4=
10+4 = 14 right ??
Answer:
Step-by-step explanation:
see the attached figure with letters to better understand the problem
we know that
In the right triangle ABD
In the right triangle BCD
remember that
m< BAD=m<CBD
therefore
equate the equations
