Answer:
B
Step-by-step explanation:
the sum of the 3 angles in a triangle = 180°
sum the parts of the ratio 3 + 3 + 4 = 10 parts
divide 180° by 10 to find one part of the ratio
= 18° ← 1 part of the ratio
3 parts = 3 × 18° = 54°
4 parts = 4 × 18° = 72°
thus the 3 angles are 54°, 54° and 72°
All 3 angles are acute angles
Hence an acute angled triangle
Answer:
1=b. 2=a
Step-by-step explanation:
Since there are corresponding angles, 1 and b will be congruent, and 2 and a will be congruent.
(E) -3, 5
<u>Explanation:</u>
Given:
equation:
Solving this equation further
Therefore, the value of x is -3, 5
We know that it costs $68 for 16 square feet of flooring. To find out how much it costs for 12, we first have to find out how much it costs for 1 square foot.
To find that, we would do $68 divided by 16, which is 4.25.
That means 1 square foot costs $4.25.
Then, we would multiply $4.25 by 12 to find how much 12 square feet costs.
$4.25 times 12 is 51.
So, it would cost $51 to have 12 square feet of flooring.
