Answer:
x=56 and the exterior angle is 116
Step-by-step explanation:
We will call the unknown angle in the triangle y. Angle y and the angle (2x +4) form a straight line so they make 180 degrees.
y + 2x+4 =180
Solve for y by subtracting 2x+4 from each side.
y + 2x+4 - (2x+4) =180 - (2x+4)
y = 180-2x-4
y = 176-2x
The three angles of a triangle add to 180 degrees
x+ y+ 60 = 180
x+ (176-2x)+60 = 180
Combine like terms
-x +236=180
Subtract 236 from each side
-x+236-236 = 180-236
-x = -56
Multiply each side by -1
-1*-x = -56*-1
x=56
The exterior angle is 2x+4. Substitute x=56 into the equation.
2(56)+4
112+4
116
Answer:
-2/45
Step-by-step explanation:
-3/5 - (-5/9)
Subtracting a negative is like adding
-3/5 + 5/9
Get a common denominator of 45
-3/5*9/9 + 5/9 *5/5
-27/45 + 25/45
-2/45
Answer:
5280$
Step-by-step explanation:
turn 340% into 3.4
2200 times 3.4 = 7480
7480-2200=5280$
Answer:
ans = 4
Step-by-step explanation:
he has 2 1\2 and 4 1\4
to find the ans, we must firstly find out his total amount of fabric, so we add the available fabric
first we add whole numbers
2 + 4 = 6
then we add fractions
1 1
--- + ---
2 4
2 + 1 3
------------- = ---
4 4
after we add the whole no and fraction
6 + 3\4 = 6 3\4
note 10 1\2 is greater than 6 3\4
so to find the part left, we
have
10 1\2 - 6 3\4
as our answer
Answer:
a = 19
Step-by-step explanation:
Given the equation of:
First, multiply both sides by 3. That will clear the denominator which makes it easier to solve for a variable:
Subtract both sides by 5 to isolate the variable:
Therefore, the value of a is 19.
