Answer:4
Step-by-step explanation:
Answer:
first you have to find the values of the two sides of the rectangle. BC=5 cm
Area of a trapezium
= 1/2 x (5+9) x (11-5)
= 42 cm^2
We are given that
In right triangle ABC, if angle A is 90 degrees, angle C is 34 degrees, and AC is 71.4, find BC.
Solution
We will first draw a diagram to illustrate the information
Above we want to find x
The method to use is SOHCAH
From the right angle triangle above we have above, we have the adjacent side and we want to find the hypotenus, so we use cosine
i.e

We need to solve for x here

Thus, |BC| = 86.1 (to the nearest tenth
Answer:
I am 99% sure that it is the first one.
Step-by-step explanation:
X=379.2/n
N=379.2/x
