18°

Step-by-step explanation:

We see that ∠3 is 90, and ∠QPS and ∠3 are supplementary so ∠QRS is also 90°. ∠QRS = ∠1+∠2 so we have that:

∠1 + ∠2 = 90°

Then we plug in the known values for angles 1 and 2:

7x-19+x+5=90

When you solve for x you get:

x = 13

Then plug x back into the equation of ∠2 to get:

13+5=∠2

Therefore, ∠2 is 18°

from looking at this i can see QT is a like which equals 180

and SPT or M∠3 equals 90 so

180-90=90 so

M∠1+M∠2=90

and M∠1=7x-19

and M∠2=x+5

so we just add these up

90=8x-14

104=8x

x=13

now we just put that into the equation for M∠2

M∠2=13+5

M∠2=18

Hope This Helps!!!

d) -1

step-by-step explanation:

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this
