The opposite angles in any inscribed quadrilateral are supplementary.
∵ ∠E + ∠R = 180°
∴ ∠R = 180 - ∠E = 180° - 74° = 106°
Answer:
m=2
Step-by-step explanation:
RS=2m+2
ST=3m+3
RT=15
m=2
RS=2(2)+2
RS=4+2
RS=6
ST=3(2)+3
ST=6+3
ST=9
Because S is in the middle of RT, if you add RS and ST together, you will get the length of RT.
6+9=15
10) 4 1/2 inches thick. You would add them together and simplify 2/4 into 1/2.
11) Yes. He needed a stick that was about 5 feet long. It is only a little longer and he could easily make it shorter.
Answer:
420 m^2
Step-by-step explanation:
Ancho: x
Largo: 2x + 2
2x + 2(2x+2) = 88
2x + 4x + 4 = 88
6x = 88 - 4
x = 84/6
x = 14
Ancho: 14
Largo : 30
Area: 14 * 30 = 420 metros cuadrados
