Answer:
x = 5
Step-by-step explanation:
Given that, exterior angles on the same side of a traversal are supplementary a Hence, sums up to 180°
Given the angles:
7x° + 11x° + 90° = 180°
18x° + 90° = 180°
18x° = 180° - 90°
18x° = 90°
x = 90° ÷ 18
x = 5
Answer:
2/3
Step-by-step explanation:
There are 6 marbles in the jar
4 are not purple
P(not purple) = marbles that are not purple/ total marbles
= 4/6 = 2/3
Answer:
351cm³
step by step explanation:
Volume of the prism:
=[1/2×(a+b)×h]×l
=[1/2×(5+8)×6]×9
=(1/2×13×6)×9
=(6.5×6)×9
=39×9
=351cm³
So you would draw an array and then subtract 1 from each side!
hope that helped
