Answer:
A. 144 degrees
B. 51 degrees
Step-by-step explanation:
38*3+30
114+30=144
39 + x = 90
x = 51
Answer:
4√3 cm^2
Step-by-step explanation:
30 60 90 right triangle
The ratio of short leg : long leg : hypo. = x : x√3 :2x
Given Hypo BC = 4 = 2 * 2
so Long leg = 2√3
Area of ABC = 1/2 (b)(h)
= 1/2 (4)(2√3)
= 4√3
Answer
4√3 cm^2
Perimeter = 3 x 4 = 12 cm (you asked from other, so I answered for you as well)
Answer:
x=4.2. If you divide 12.6 by 3, you get 4.2
The solid figure is represented by the second option.
Step-by-step explanation:
- The solid figure in the question is a cuboid.
- On opening, it will have 6 faces, each of which will be a rectangle.
- All the corners or edges will have 90° or right angles.
- Also, on opening, one side will have 2 other faces attached to it on top and bottom which is seen in the second figure.
<u><em>The answer is 32.0 cm.</em></u>
<u><em>I found the missing lengths and just added them all so:</em></u>
<u><em>9+7+5+3+4+4= 32 cm or 32.0 cm.</em></u>
<u><em>Hope this helps!</em></u>
