Answer:
8−4 a
Step-by-step explanation:
x=g(h(a−4))
h(a−4)=−2(a−4)−5 = −2 a+8−5=3−2 a
Apply g.
g(h(a−4))=g(3−2a)=2(3-2a)+2=6−4a+2
Answer:
The value of x is
.
Step-by-step explanation:
It is given that hypotenuse is
. So, the legs would be x and 8.
Let's use Pythagoras theorem,

Plug in the numbers to solve for x.

Simplify it

Subtract both sides 64.

Take square root on both sides
x=
We can not simplify the radical.
So, let's keep this as answer.
5x=15
X=3
2(3)+y=5
Y= -1
(3,-1)
Answer:

Step-by-step explanation:
step 1
Find the measure of arc EH
we know that
----> by complete circle
substitute the given values



step 2
Find the measure of angle EYH
we know that
The measurement of the outer angle is the semi-difference of the arcs which comprises

substitute the values
