Answer:
4. 27
Step-by-step explanation:
11-10=1 which is <=16
15-10=5 which is <=16
26-10=16 which is <=16
27-10=17 which isn't <=16
Therefore 27 doesn't satisfy the inequality
Answer:
D
A right triangle is a triangle that has one 90 degree angle, so looking at the options i would say D
Step-by-step explanation:
Answer:
DEC+DEF=180
DEC=180-116
DEC=64°
in triangle DCE
angle D+angle C+angle E=180
7y+6+4y+64=180
11y+70=180
11y=180-70
11y=110
y=110/11
y=10°
angle C=4y
=4(10)
=40°
Answer:
A
Step-by-step explanation:
Given
5(x - 7) = 55, then using the distributive property, that is
a(b - c) = ab - ac, then
5x - 35 = 55
Answer:
x = 4
Step-by-step explanation:
Using the sine ratio on right triangle KJL
and the exact value sin30° = 
sin30° = 
= 
= 
= ( cross- multiply )
2JL = 8
( divide both sides by 2 )
JL = 4
---------------------------------------------------------
Using the sine ratio in right triangle JLM
and the exact value sin45° = 
sin45° = 
= 
= 
= ( cross- multiply )
x × = 4 ( divide both sides by
x = 4
