Answer:
It should be 60 degrees
correct me if wrong but since it's supplementary, you subtract 155 - 35 then from 180 and you get 60
Im not 100% about this tho but like 75% sure
Answer:
3400
Step-by-step explanation:
if you add it all up in cm, which is 340cm then divide by 10 you get 3400.
Sophia is 12. Four times that is 48. If her mother is 5 years less than this, she is 43.
(12 x 4) - 5 = 43
Answer:
105degrees
Step-by-step explanation:
Using the theorems that states that the sum of the opposite side of the quadrilateral is 180degrees, hence;
<RST + <TQR = 180
5x+15 + 4x+ 3 = 180
9x + 18 = 180
9x = 180 - 18
9x = 162
x = 162/9
x = 18
Since <RST = 5x+15
<RST = 5(18) + 15
<RST = 90 + 15
<RST = 105degrees
Hence the measure of <RST is 105degrees
