Step-by-step explanation:
you first convert them to improper fractions, which is 14/3 and 7/3. Then, you multiply the reciprocal and get 14/3x3/7, and get 42/21. Simplify, and you get 2.
Answer:
−(3x−2)(7x+4)
Step-by-step explanation:
Hello Tbeck227, how to find the angle measure of an isosceles triangle if you only know the side lengths is, <span> for all the angles, though it would be
unreasonable to use it for all three, since once we know two the third
is easy. Lubin suggested using the Cosine Law for the first calculation
and the Sine Law for the second. This is faster than Cosine Law done
twice. The suggestion is to use the Cosine Law to determine the angle
opposite a largest side.</span>
Answer:
Area of parallelogram=Base*Hieght
=AD*JC
=9*4
=36
Answer:
x ≈ 54.8°
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan x = 
= 
= 
, then
x = 
( ) ≈ 54.8° ( to the nearest tenth )
