Answer:
AB = 5
BC = 12
AC = 13
Step-by-step explanation:
A rectangle is a quadrilateral and therefore, opposite sides are parallel and congruent to each other. Thus:
AB = CD = 12
AB = 12
BC = AD = 5
BC = 5
AC is a diagonal of the rectangle, use Pythagorean theorem to find it's length as follows:
AC² = AD² + CD²
Plug in the values
AC² = 5² + 12²
AC² = 169
AC = √169
AC = 13
Y= -3x+8
y= 3x+2
both points meet at points ( 1 , 5 )
solve algebraically:
-3x+8=3x+2
+3 +3
_________
8=6x + 2
-2 -2
_________
6/6= 6x/6
x=1
y=3(1)+2
y=3+2
y=5
points: (1,5)
Answer:
a. Same Side Interior Angles
b. Corresponding Angle
c. Alternate Exterior Angle
d. Alternate Interior Angles
e. 20
f. 70
Step-by-step explanation:
e. Corresponding angle add up to 90 degrees. Which you have to subtract 110 to 90 and is 20
f. same side interior angle adds up to 180 degrees. Which you have to subtract 180 to 110 and it is 70
Answer:
9, 2
Step-by-step explanation:
Pull out the numbers being multiplied by 8
Ratio 4:7
If there are 8 red then number of yellow, y = 8 ×7/4=14
