Answer:
121.205882353
Step-by-step explanation:
Put it in a calculator
Sin of an angle is opposite leg divided by hypotenuse.
sin B= 12 / 13
tan of an angle is opposite leg divided by adjacent leg
tan B= 12 / 5
cos of an angle is adjacent leg divided by hypotenuse
cos B= 5 / 13
Answer:
h = 9 cm.
Step-by-step explanation:
V = kBh where k is the constant of variation.
From the given info:
32 = k*16*6 = 96k
So k = 32/96 = 1/3.
So we have the equation of variation:
V = 1/3Bh
When V = 60 B = 20, so:
60 = 1/3 20h
20h = 60 * 3 = 180
h = 180 /20 = 9.
Answer:
45 degrees
Step-by-step explanation:
A straight line is an angle with a measure of 180°, but becasue it looks like we have two angles that create the 180° angle, therefore, it is a supplementary angle.
Knowing this
2X = 90° (right angle)
so (2X) + (2X) = 180° (supplementary angle)
Therefore, to find X you can do
2X = 90
divide by 2 on both sides (to isolate the variable we are trying to find which is X)
and you get....
X= 45 becasue 2 times 45 equals 90
answer: X=45°
