3. 180 - (53+68) = 59
The answer is B. 59°
4.
Part A: The measure of a is 70°.
Explanation: The angle sum in any triangle is 180°. 70 + 40 is 110. To find the final angle, subtract 110 from 180. 180 - 110 = 70
Part B: The length of x is 5m.
Explanation. The triangle is an isosceles triangle. We know this because the two angles on the base are equal. Since this is an isosceles triangle, the two longer sides are the same length. Therefore: x = 5 m.
Answer:
d
Step-by-step explanation:
Volume can be described as the total amount of space that is in a closed surface. this amount of space is usually three dimensional. Volume is usually measured in m³ or cm³ or in³
For example, the volume of a rectangular box given the following dimension : length - 3cm
breadth - 8cm
height - 10 cm
volume = length x width x height = 8 x 3 x 10 = 240 cm³
Answer:
a = 4
b = 4
Step-by-step explanation:
This is a special right triangle with angle measures of 45° 45° 90° and side lengths x x x√2
