we know that
The sum of the internal angles in the triangle must be
degrees
see the attached figure with letters to better understand the problem
Step 
<u>Find the measure of the angle x</u>
In the triangle ABC

solve for x



therefore
<u>the answer Part a) is</u>
the measure of angle x is 
Step 
<u>Find the measure of the angle z</u>
we know that
--------> by supplementary angles
substitute the value of x



therefore
<u>the answer Part b) is</u>
the measure of angle z is 
Step 
<u>Find the measure of the angle y</u>
In the triangle ACD

solve for y




therefore
<u>the answer Part c) is</u>
the measure of angle y is 
Answer:
2+7_t×y+9 je pense que c la reponses
Answer:mark me a brainiest pls
that is a linear function search it up on Google youl get the answer from there
40,768/52 (weeks per yr)= 784
We will consider the following possibilities:
Wins none, wins first only, wins second only, wins both
a) Wins none:
Chances are: 75% x 65% = 48.75%
Thus, there is a 48.75% chance that the horse will sell at $15,000
b) Wins first only:
Chances are: 25% x 65% = 16.25%
c) Wins second only:
Chances are: 75% x 35% = 26.25%
Thus, the chances of the horse selling at $60,000 are 16.25 + 26.25
= 42.5%
d) Wins both:
Chances are: 25% x 35% = 8.75%
The chances that the horse will sell at $100,000 are 8.75%
