Answer:flowchart proof
Step-by-step explanation:
Step-by-step explanation:
1. No: angles add to more than 180 deg.
2. Yes: each side's length is between the sum and difference of the lengths of the other two sides.
3. No: not every side's length is between the sum and difference of the lengths of the other two sides.
4. Yes: for example, place the 50 deg angle between the two given sides. Another side will then make the triangle.
5. Yes: for example, use 3 cm as the short leg in a 30-60-90 right triangle.
<h2>135 cubic feet of concrete are required to create the platform.</h2>
Step-by-step explanation:
The dimension of lower step is 6 ft× 3 ft× 1.5 ft
and the dimension of upper step is 6 ft ×(9-3)ft × (1.5+1.5)ft = 6 ft × 6 ft ×3 ft
Therefore concrete are required to make lower step = (6×3×1.5) cubic feet
= 27 cubic feet
and concrete are required to make upper step = (6×6×3) cubic feet
=108 cubic feet
<h3>∴(108+27) cubic feet =
135 cubic feet of concrete are required.</h3>
Answer:
cos = adjacent/hypotenuse
3/square root13
now you do square root 13 x3 divided by square root 13^2
= 3square root13/13
