Evaluate angles d and e, giving reason for your answer​
Jobisdone [24]

Answer:

Ok so we know that the angle on top is 110 since the angle above is the same.

we also know that all the angle of the triangle will add up to 180 so

D+(180-E)+110=180

we also know that d and the angle directly across are the same so

180-110=70

70divide by 2 equals 35

now we subtratch 35 from 180 to get 145

E=145

D=35

Your Welcome

PLS PLS HELP! I need the answer ASAP
Nat2105 [25]

Answer:

E

Step-by-step explanation:

-x +6 ≥  -3x - 4

Add 3x to both sides

-x + 3x + 6 ≥ -4

Combine like terms

2x + 6 ≥ -4

Subtract 6 from both side

2x ≥ -4 - 6

2x≥ -10

Divide both sides by 2

x ≥ -10/2

x ≥ -5

Set up an algebraic equation then solve. 1. When 3 is subtracted from the sum of a number and 10 the result is 2. The sum of 3 t
Inessa05 [86]

Answer:

( x+10)-3= 2

x+10= 5

x= -5

3x+12= 3

3x= -9

x= -3

3( x+6 )= 5x

3x+ 18 = 5x

2x= 18

x =9

w= l-4 y= x-4

perimeter= 2l+ 2w

2(2x) + 2( x-4)

4x+2x-8 = 72

6x= 72+8

6x= 80

x= 13.3 width = 9.3 length = 13.3

4x=48

x = 12

each 2= 24
