Area of a Triangle = 1/2 * b * h
A = 1/2 * 4 * 5
A = 1/2 * 20
A = 10 units
In short, Your Answer would be Option C
Hope this helps!
Answer:
x = 65
Step-by-step explanation:
using the Altitude- on- Hypotenuse theorem
(leg of big Δ )² = (part of hypotenuse below it ) × (whole hypotenuse)
x² = 25 × 169 = 4225 ( take square root of both sides )
x = = 65
The answer would be D. It would be $42 in the end if you picked D.
The value of y from the given trig expression is pi/3 rad
<h3>Trigonometry identity</h3>
These identities are expressed in terms of sine, cosine and tangent
Given the expression
Expand sin(x+y)
sin(x+y) = sinxcosy + cosxsiny
Compare both equations
cosy = 1/2
y = arccos(1/2)
y = 60 degrees
y = pi/3 rad
Hence the value of y from the given trig expression is pi/3 rad
