Answer:
It's 90
Step-by-step explanation:
Answer:
b. (√15)/4
Step-by-step explanation:
Since Sin Ф = (opposite side)/Hypotenuse, we have 2 sides of a right triangle.
Use Pythagorean theorem to solve for the missing leg (the adjacent side)
1² + b² = 4²
1 + b² = 16
b² = 15
b = √15
So the adjacent side is √15, so Cos Ф = (√15)/4
Answer:
A
Step-by-step explanation:
Answer:
m = 3
n = 14
p = 2
Step-by-step explanation:
7/x-3/2=(n-mx)/px
(7*2-3*x/2)/2x=(n-mx)/px
=>(14-3x)/2x = (n-mx)/px
now we will compare
LHS and RHS with terms containing X and terms not containing x
so
14 = n
-3x = -mx
m = 3
2x = px
p = 2
Thus,
values for m, n, and p
are 3,14 and 2 respectively.
They are similar by the Side-Side-Side Theorem.
The smaller triangle is 3/4 of the second triangle:
90/120; divide each by 10, = 9 / 12 which simplifies to 3/4
135/180; divide each by 15, = 9 / 12 which simplifies to 3/4
117/156; divide each by 13, = 9 / 12 which simplifies to 3/4
