Answer:
2a +2b +4
Step-by-step explanation:
The perimeter is the sum of the lengths of the three sides. If x represents the length of the third side, then ...
(3a +8) +(5a +b) +x = (10a +3b +12)
Subtracting from the equation everything on the left side that is not x, we get ...
x = (10a +3b +12) -(3a +8) -(5a +b)
= a(10 -3 -5) +b(3 -1) +(12 -8)
= 2a +2b +4
The length of the third side is 2a +2b +4.
Answer:
Step-by-step explanation:
Let
x ----> the measure of one angle of the triangle
y ---> the measure of the second angle
z ----> the measure of the third angle
we know that
The sum of the measure of the interior angles in any triangle must be equal to 180 degrees
-----> equation A
One angle of a triangle measures 10 degrees more than the second
----> equation B
The measure of the third angle is twice the sum of the first two angles
---> equation C
substitute equation B in equation C
----> equation D
substitute equation D and equation B in equation A
solve for y
Find the value of x
Find the value of z
therefore
The answer is 6. All you do is multiply the types of peanut butter with the type of jelly.
Answer:
c. x=3
Step-by-step explanation:
Given:
7x < 21
Divide both sides by 7
7x / 7 < 21 / 7
x < 21/7
x < 3
x = 3
Check:
7x < 21
7(3) < 21
21 = 21
Answer:
cos r/q is the answer,
Step-by-step explanation:
this can be seen when you elaborate sin=opposite/hypotenus and tan=opposite/adjacent by referring to the right angle triangle .
then, apply values of adjacent dan hypotenuse to cos
