Answer:

Step-by-step explanation:

The length of the unmarked side of the triangle is found by using Pythagoras:

x sqrt (10^2 - 6^2)

= sqrt 64

= 8.

The length of the curved part = 1/2 * pi * 10 = 5pi

Perimeter = 8 + 6 + 5pi

= 14 + 5pi

Answer:

D. 14 + 5π inches

Step-by-step explanation:

1. solve for the side of a triangle using Pythagorean = $\sqrt{(10^2 - 6^2)}$ = 8 in.

2. circumference of a half circle = πd /2 = π*10 / 2 = 5π in.

3. total perimeter = (8 + 6) + 5π = 14 + 5π

therefore, the answer is D. 14 + 5π inches

Use the net as an aid to compute the surface area of the triangular prism.

Harrizon [31]

Answer:

Option C. $564\ mm^{2}$

Step-by-step explanation:

we know that

The surface area of the triangular prism using the net is equal to the area of two triangles plus the area of three rectangles

$SA=2(\frac{1}{2})(10)(12)+2(13)(14)+(10)(14)$

$SA=60+364+140$

$SA=564\ mm^{2}$

Triangle A B C is shown. The length of A B is 12, the length of B C is 24, and the length of C A is 12 StartRoot 3 EndRoot

jeka57 [31]

Answer: The answer is B.

Step-by-step explanation:

First of all, if you just look at the angles, you can already tell that angle A is the right angle, in which you can then cross out A and C. Now you are down to B or D. This was tough but if you remember that the longer leg is square root of 3 times the shorter leg then you can tell that the included angle between the side showing 12 and the side showing 24 is the 60 degree angle. This leaves you to tell that the other angle is 30 degrees.

I hope this helps ;)
