Answer:
hey,its option a
Step-by-step explanation:
because angle F= angle M and angle G= angle L
and angle H= angle N
To know third angle in ∆HGF
,we know sum of all angles in a triangle is 180°
______________________________
let angle H be unknown value x
x+51+36=180
x=180-87 ---------------- 1
similarly in ∆MNL
let angle be y
51+36+y=180
y=180-87----------------2
_______________________________
From 1&2 we observe qngle x= angle y
by AAA SIMILARITY THEY ARE SIMILAR
Answer:

Step-by-step explanation:
Apply pythagorean theorem:
ABD is a right triangle with angle ADB = 90
hence AD =
where BD = 10 because it is half of BC
AD =
= 
Answer:
B and J switch because J is a repeating number and repeating numbers are irrational because they don't have a definte end. Other than that, you are good!
Step-by-step explanation:
Answer:
g=3
Step-by-step explanation:
f(g) = g^2 +3g
Let f(g) = 18
18 = g^2 +3g
Subtract 18 from each side
18-18 =g^2 +3g-18
0 = g^2 +3g-18
Factor
0 = (g+6) (g-3)
Using the zero product property
g+6 =0 g-3 =0
g = -6 g =3
The only solution listed is g=3
B. The 3 is repeated in a function every x has exactly one y. Hope this helped !
