Answer:
<h2>
A = 132 cm²</h2>
Step-by-step explanation:
Area of the figure is a sum of area of rectangle 4 cm × 7 cm and trapezoid with bases of 19 cm i 7 cm and altitude of 8 cm.
Therefore:
![A=7\cdot4+\dfrac{7+19}2\cdot8=28+26\cdot4=132](https://tex.z-dn.net/?f=A%3D7%5Ccdot4%2B%5Cdfrac%7B7%2B19%7D2%5Ccdot8%3D28%2B26%5Ccdot4%3D132)
Answer:
$1040
Step-by-step explanation:
if you buy an item at $1300 with 20% discount
1300 - 260 = 1040 dollars
Answer:
32
Step-by-step explanation:
In order to find the measure of angle A we must first find x
If you didn't know, supplementary angles add up to equal 180
Hence, 2x - 16 + 5x + 28 = 180
( Note that we just created an equation that we can use to solve for x )
We now solve for x using the equation that we created
2x - 16 + 5x + 28 = 180
Combine like terms
7x + 12 = 180
Subtract 12 from both sides
7x = 168
Divide both sides by 7
We're left with x = 24
Now to find Angle a
To find Angle A we simply substitute 24 for x in 2x - 16
* Substitute 24 for x *
2(24) - 16
Multiply
48 - 16
subtract
/_ A = 32
The answer is B) 26 because it would have to add up to 90
A ) The angle formed by 2 consecutive radii:
Ф= 360° : 8 = 45°
b ) The angle formed by a radius and a side of a polygon:
α = (180° - 45°): 2 = 135° : 2 = 67.5°
Answer:
B ) 45°, 67.5°
