The answer is in Standard Form -3y^2-6y-17
R=4
theta=pi/2
x= r cos(theta) = 4 cos(pi/2) = 4(0) = 0
y = r sin(theta) = 4 sin(pi/2) = 4(1) = 4
(0,4) is the answer.
Answer:
5x^2
Step-by-step explanation:
12 can be taken out from the top and bottom then for the x you subtract
m∠Z = 55°
Solution:
Given m∠A = 75° and m∠B = 50°
Let us first find the m∠C.
Sum of the angles of the triangle is 180°.
In ΔABC,
m∠A + m∠B + m∠C = 180°
⇒ 75° + 50° + m∠C = 180°
⇒ 125° + m∠C = 180°
⇒ m∠C = 180° – 125°
⇒ m∠C = 55°
Given ΔABC ≅ ΔXYZ.
Corresponding parts of congruence triangles are congruent.
⇒ m∠Z = m∠C
⇒ m∠Z = 55°
Hence, m∠Z = 55°.
Answer:
Yes because both the numerator and the denominator are multiplied by 4 to get to the resulting fraction.
