let 2nd angle = x
then 1st angle = 2x-15
then you have 90 = x + 2x-15
2x +x = 3x
so now 90 = 3x-15
add 15 to each side
105=3x
x = 105/3 = 35
1st angle = 35 degrees
2nd angle = 2(35) - 15 = 70-15 = 65
Answer:
x < 293 / 700
Step-by-step explanation:
−35x + 15 > 7/20
Multiplying all through by 20
-700x + 300 > 7
-700x > 7 - 300
-700x > -293
Divide all through by 700
- x > - 293 / 700
Multiply all through by -
x < 293 / 700
True: A face of a polyhedron is simply a flat boundary that helps forms the 3D solid.
Answer:
I believe the correct options are 1, 4, and 5.
Answer:
459
Step-by-step explanation:
because 3^5 is 243 and 6^3 is 216 then add up 243+216=459
