Answer:
x = 30°
Step-by-step explanation:
We know that the sum of all of the interior angles of a triangle is 180°, therefore, we can write the following equation:
x + 2x + 3x = 180
6x = 180
x = 30°
Answer:
Should be around 4.5
Step-by-step explanation:
If you round 31.53 to the nearest ten dollars, you get 30, 15 percent of 30 is 4.5
Answer:(A.)
Step-by-step explanation:The reason why its a its because that 13x8=104x17=1,768/3=589.3. Therefore 589.3 can not be round to the nearest tenth.
Given that length = 14 cm, width = 7 cm, and height(which was not mentioned in the question) is 1.66 cm, we are tasked to f<span>ind the lateral area and the surface area of the box.
To find the lateral area, we need to add the area of the sides of the 3D figure.
L = 2(1.66)(14) + 2(1.66)(7)
=46.48 + 23.34
=69.72 </span><span> ≈ 70 cm^2
</span>To find the surface area,
SA = 2(1.66)(14) + 2(1.66)(7) + 2(14)(7)
=46.48 + 23.24 + 196
=265.72 ≈ 266 cm ^2
The answers are <span>70cm^2 and 266cm^2.</span>
