Answer:
The measures of the angles are 50° and 130°
Step-by-step explanation:
Let
x ----> the measure of one angle
y ----> the measure of the other angle
we know that
If two angles form a linear pair , then their sum is equal to 180 degrees
-----> equation A
----> equation B
substitute equation B in equation A
solve for y
Find the value of x
The measures of the angles are 50° and 130°
Y = x + 1.75...so we sub in x + 1.75 for y in the other equation
4x - 2y = 4
4x - 2(x + 1.75) = 4....distribute thru the parenthesis
4x - 2x - 3.5 = 4....add 3.5 to both sides
4x - 2x = 4 + 3.5...simplify
2x = 7.5....divide both sides by 2
x = 7.5 / 2
x = 3.75
now we sub in 3.75 for x in either of the original equations to find y.
y = x + 1.75
y = 3.75 + 1.75
y = 5.5
so ur solution is : (3.75,5.5) <==
Answer:
6
Step-by-step explanation:
6 divided by 2 is 3
Answer:
Answer is -759/5
Step-by-step explanation:
To find the sum of a finite geometric series, use the formula,
Sn= a1-a1r^n/ 1-r
where n is the number of terms, a1 is the first term and r is the common ratio .
common ratio = a2/a1
S8=3-3(-2/3)8 / 1-(-2/3)
S8 = 3-(-2)8/ 1+ 2/3
S8= 3-256/ 3+2/3
S8= -253/5/3
S8= -253*3/5
S8= -759/5
