The first pair because one is a triangle and the second is a acute triangle
Answer:
how do you need help. what's the problem
Step-by-step explanation:
Step-by-step explanation:
3. The triangle that makes up the square is a 45-90-45 triangle so x = 45°. Using Pythagorean theorem,
2y^2 = 12 ---> y^2 = 6
or
y = √6
4.This is an equilateral triangle of side 11 so
y = 11/2
To find x, use the definition of sine 60:
sin 60° = opp/hyp
= x/11
or
x = 11sin60° = (11√3)/2
-0.03125 this would be the answer to that problem
B is 26
c is 15
X is 80
g is 30
x is -5
W is -4
r is 45
k is 12
f is 50
