Answer:
Step-by-step explanation:
1- angle JZF
supplementary angle or straight angle =180 degree
HZJ+JZF=HZF straight angle
2- JZA
complementary angle or right angle =90 degree
HZJ+JZA=HZA ( right angle)
if angle HZJ=38 degrees
HZJ+FZJ=180
FZJ=180-38
<h2>FZJ=142 degrees</h2>
HZG+HZJ=180
HZG=180-38=142 degrees ( which is vertical angle to FZJ and equal to it)
HZG=142 degrees
AZJ+HZJ=90 degrees
AZJ=90-38
AZJ=52 degrees
the answer is the second choice
Answer:
sin x = 3/5
cos y = 3/5
sin x and cos y are equal
Step-by-step explanation:
First we need to find the length of the hypotenuse
We can use the Pythagorean theorem
a^2+ b^2 = c^2 where a and b are the legs and c is the hypotenuse
6^2 +8^2 = c^2
36+64 = c^2
100 = c^2
Taking the square root
sqrt(100) = sqrt(c^2)
10 = c
The hypotenuse is 10
Since this is a right triangle we can use trig functions
sin x = opp side/ hypotenuse
sin x = 6/10 = 3/5
cos y = adj / hypotenuse
cos y = 6/10 = 3/5
sin x and cos y are equal
Answer:
c=8p
Step-by-step explanation:
So, we know that 1 pound of chocolate will cost $8. Felipe is going to buy "p" pounds of chocolate, and "p" means "any number"; so Felipe is going to buy any number of pounds of chocolate.
The formula we would use to calculate this is cost of one pound of chocolate multiplied by number of pounds of chocolate. And the way we can form this algebraically is by writing c=8p.
The "c" stands for total cost and we don't have to put the multiply sign when using algebra, as long as the figures are touching.
