Sin(45), or sin(pi/4) = sqrt(2)/2. So sin^2(45)= (sqrt(2)/2)^2, which is 1/2.
Answer:
5
Step-by-step explanation:
multiply 1/10 by 50
1/10×50= 5
Given:
m∠CXD = 30°
m∠DXE = 30°
To find:
The measure of angle CXE.
Solution:
The measure of angle CXE is sum of the measures of angle CXD and DXE.
⇒ m∠CXE = m∠CXD + m∠DXE
⇒ m∠CXE = 30° + 30°
⇒ m∠CXE = 60°
The measure of angle CXE is 60°.
Answer:110 degrees
Step-by-step explanation:
Answer:
= 
(3n + 7)
Step-by-step explanation:
We require to find the first term a₁ and the common difference d
The n th term is given by 3n + 2, thus
a₁ = 3(1) + 2 = 3 + 2 = 5
a₂ = 3(2) + 2 = 6 + 2 = 8
d = 8 - 5 = 3
= [ 2a₁ + (n - 1)d ], substitute values
= [ (2 × 5) + 3(n - 1) ] = (10 + 3n - 3) = (3n + 7)
