Answer
Find out the perimeter of the isosceles triangle.
To prove
As shown in the figure.
P(0,4) , Q(-2,0) and R(2,0) are the vertices of the triangle PQR.
Formula
As P(0,4) and Q(-2,0)
In the isoceles triangle the two sides of the triangles are equal .
Therefore PQ = PR
As Q(-2,0) and R(2,0)
QR = 16 unit
5 times 12 equals 60 and 1 left over which is the remainder you do
Answer:
x = 35°
Step-by-step explanation:
The question is as following
cos x = sin(20 + x)° and 0° < x < 90° , find X?
==============================================
cos x = sin(20 + x)°
sin and cos are co-functions,
which means that: cos x = cos [90 - (20 + x)]
∴ x = 70 - x
∴ 2x = 70
∴ x = 35°
======================
Note: cos θ = sin ( 90 - θ )
A box has 6 sides so you multiply 16.7 and 6 and you’ll get 100.2
ANSWER IS 100.2in
Answer:
x = 21
Step-by-step explanation:
Based on the inscribed angle theorem, we would have:
120° = 2(3x - 3)°
Solve for x
120 = 2*3x - 2*3
120 = 6x - 6
Add 6 to both sides
120 + 6 = 6x
126 = 6x
Divide both sides by 6
126/6 = x
21 = x
x = 21
