Answer:

m∠1 +m∠8 = 90°

Step-by-step explanation:

There is no necessary sum relation between angles 3 and 5 or angles 7 and 10. The only thing you can say about those angle pairs is ...

∠3 + 90° = ∠5

∠10 +90° = ∠7

Angles 8 and 9 are congruent, so don't have any necessary sum.

Angle 1 is congruent with angle 3, which is complementary to angle 8, so we must have ...

m∠1 +m∠8 = 90°

Solve the equation 7 − 2x = 19.

Karolina [17]

Answer:

-6

Step-by-step explanation:

firstly arrange whole equation,

-2x+7=19

Now, Transpose 7 to RHS (right hand side)

-2x=19-7

-2x=12

Further, seperate coefficient -2 from x

and transpose it to RHS and divide them

x=12/-2

Hence, x= -6
