Answer:
Step-by-step explanation:
In the figure you can identify up to 3 straight triangles.
To solve the problem, write the Pythagorean theorem for each triangle.
<em>Triangle 1</em>
<em>Triangle 2</em>
<em>Triangle 3</em>
Now substitute equation 2 and equation 3 in equation 1 and solve for y.
substitute the value of y in the second equation and solve for z
Answer:
ASA angle side angle
Step-by-step explanation:
DE=JH(given)
angle E= angle H (given)
angle D=angle J (given)
It is option c. Because when we substitute x for -1 we get the remainder as 1.
Answer:
a= 4
b= -1
c= 10
Step-by-step explanation:
First we start by multiplying both sides of 1/2c = 5 by 2.
c = 10
Add b to both sides of the last equation to make it a=b+5
knowing these two things, we can plug them into the first equation like this:
2(b+5) + b + 10 = 17
then you solve for b:
distribute the 2
2b + 10 + b + 10 = 17
combine like terms
3b + 20 = 17
subtract 20 from each side
3b = -3
divide by 3
b = -1
then you can plug that into the last equation again so a - (-1) =5
Subtracting a negative is the same as adding so its a + 1 = 5 or a = 4
