Answer:
Angle 1= 147
Angle 2= 33
Step-by-step explanation:
(4a+7) + (a-2) = 180
4a+7+a-2=180
5a+5=180
5a=175
a= 35
plug in 35 for A to find measurements
4(35) +7 = 147
(35) -2= 33
The total surface area of the triangular prism that has a height of h and the side length of a is given below.
<h3>What is a triangular prism?</h3>
A triangular prism is a closed solid that has two parallel triangular bases connected by a rectangle surface.
A box is in the shape of an equilateral triangular prism.
If the box is to be covered with paper on its lateral sides.
Let a be the side length of the equilateral triangle and h be the height of the prism.
Then the surface area of the triangular prism will be
Surface area = 2 × area of triangle + 3 × area of the rectangle
The area of the triangle will be
The area of the rectangle will be
Then the total surface area will be

Answer:
1. None of the angles
2. Is not
3. Is not
Step-by-step explanation:
We can see if the triangles are congruent by ASA (angle, side, angle)
We find ∠F in DEF by 180-(64+78)=38 and 38 doesn't equal 39 so they are not congruent.
Answer:
6 and 8
Step-by-step explanation:
The hypotenuse of a 30°-60°-90° triangle measures 10 inches.
To find the length of one of the legs, we use the idea of Pythagorean Triples.
Pythagorean Triples are any set of three numbers that satisfies the Pythagorean Theorem. Some common examples are:
- 3, 4 and 5
- 5, 12 and 13
- 9, 40 and 41
Note that in a Pythagorean Triple,
- The longest length is always the Hypotenuse.
- New Triples can be formed from product of existing triples.
In our given triangle, the Hypotenuse=10 Inches
Consider the Pythagorean Triple 3,4, and 5
- 5 is the Hypotenuse
- Multiply the Triples by 2, we obtain:
- 6, 8 and 10 (in which 10 is the hypotenuse)
Therefore, 6 and 8 could be the length of a leg of the 30°-60°-90° triangle.
