Answer:c
Step-by-step explanation:
Answer:
70°
Step-by-step explanation:
since two lengths are equal to 3.5 that’s means there’s are two equal angles (55° and 55°)
a triangle adds up to 180°
so to find x we set this up:
x +55 +55 = 180
x + 110 = 180
x = 70°
Answer:
Area will be 2(lb + bh + hl)
So 2*(12*9 + 9*4 + 4*12)
384 sqft
Answer:
I think it's B. 5/9(F -32) < 140
Step-by-step explanation:
Answer:
a
Step-by-step explanation:
sec (thita) = squrt (5)
squaring on both sides:
sec^2 (thita) = 5 - equation 1
1 + tan^2 (thita) = 5
tan^2 (thita) = 4
tan (thita) = 2.
= tan (thita) - squrt(5)sin(thita)
= 2 - squrt(5) x 2/ squrt(5)
= 0
from eqn - 1
sec(thita) = squrt(5)
cos(thita) = 1/ squrt(5)
sin(thita) = squrt ( 1- 1/(squrt (5))^2)
sin(thita) = 2/ squrt(5) .
