Answer:
x=136
Step-by-step explanation:
To find the measure of the sum of the interior angles use the formula (n-2) times 180 where n is the number of sides.
A quadrilateral has 4 sides. (4-2) times 180. 2 times 180=360
The sum of the interior angles of a quadrilateral is 360.
x+47+95+82=360
x+ 224 = 360
x= 136
Answer:
x = 25
Step-by-step explanation:
<em>Step 1: Identify the similar triangles</em>
Triangle DQC and triangle DBR are similar
<em>Step 2: Identify the parallel lines</em>
QC is parallel to BR
<em>Step 3: Find x</em>
DQ/QB = DC/CR
40/24 = x/15
x = 25

Answer:
304
Step-by-step explanation:
find the area of each side, then add together
top and bottom are 10*8= 80 80*2= 160
front and back are 10*4=40 40*2=80
left and right sides are 8*4=32 32*2=64
160+80+64=304
Sum means addition
negative 18 means -18
a number can be x
Sum of negative 18 and x should be 11
thus the equation is
Answer:
= 221
Step-by-step explanation:
Lenght = 250
Width= x
Perimeter = 2 (l+b) = 942
2 x (250 +x) = 942
500 + 2x = 942
2x = 942 - 500= 442
x = 442 /2 = 221
I hope Im right!!
