3x=105
x=35
Answer:
The area of the rectangle is 40 and the area is the triangle is 20 therefore, the area of the shape is 60
Step-by-step explanation:
Rectangle:
8cm x 5cm = 40cm
Triangle <em>(</em><em>1</em><em>/</em><em>2bxh</em><em>)</em>
The base of the triangle would be 8 cm as the top and the bottom of the rectangle is the same width. The height was given to be 5 cm (<em>note the height is the dotted line</em>) Therefore the area of the triangle is half the base which is (8×1/2 = 4) times the height (5); which is 20.
Answer:
b = 22
Step-by-step explanation:
Here b represents the length of the hypotenuse, and 11 is the length of the side opposite the 30 degree angle. We want to find the value of b. We use the sine function here because we have the angle measurement (b), the angle 30 degrees and the "opposite side" 11:
sin 30 degrees = (1/2) = 11/b, which, if inverted, is 2 = b/11, or b = 22
