Answer:
A ≈ 5.6
Step-by-step explanation:
The area (A) of the triangle is calculated as
A = × PQ × PR × sin P
= 0.5 × 5.2 × 2.8 × sin50°
≈ 5.6 ( to 1 dec. place )

Answer:
x = 5
Step-by-step explanation:
Given:
a = x
b = 12
c = 13
Work:
a² + b² = c²
x² + 12² = 13²
x² + 144 = 169
x² = 25
x = 5
Answer:
Because tan represents from θ (theta), the equation should be
=
. Let's leave this equation like that. Now, we need to find the unknown side length, x. We need to use Pythagorean Theorem, because we're given the other two side lengths. The equation should be
. X should equal ±8 or 8, because a side length can't be a negative value. Now, we can plug in 8 into the equation to get
.
