let the unknown side be x , so we have :
25^2 = 20^2 + x^2
625 = 400 + x^2
x^2 = 625 - 400
x^2 = 225
x = √225
x = 15
Step-by-step explanation:
12+3y+2=0
=14+3y=0
=3y=0-14
=3y=-14
=y=-14/3, -4 2/3
Answer:
3 my guy
Step-by-step explanation:
Answer:
152 - 4d
Step-by-step explanation:
You had $152
$4 is spent each day
Let d represent the days
Since the money at hand is $152 and $4 is taken away each day then, the algebraic expression which models this situation is
= 152-4d
Answer:
15:17
Step-by-step explanation:
Since the triangle has a right angle, we may find the length of the unknown side using the trigonometric notations SOH CAH TOA where
SOA stands for
Sin Ф = opposite side/hypotenuses side
Cosine Ф = adjacent side/hypotenuses side
Tangent Ф = opposite side/adjacent side
With respect to ∠B given that ∠D=90°,
BD is the adjacent side
CB is the hypotenuse side
and DC is the opposite side
Hence Sin B = 15/17
