The sum of a polygon's angles are 540.
When you add all the angles together here, you get 456.
Now subtract 456 from 540.
540 - 456 = 84
Answer:
128cm
Step-by-step explanation:
since there are 4 triangles that have an area of 8*4 each, you can multiply 8*4 together to get 32. Then you would multiply 32 by 4 to get the entire area of the whole figure.
3,807,000 + 4,339,000= <span>8,146,000
or if you wanted it like this:
3,807,412 + 4,339,789 = </span><span>8,147,201 (8,147,201 Rounded)</span>
Answer:
x= 3 so it should be 22 but thats not an option....
Step-by-step explanation:
Answer:
i) 7x + 8 = -90
<=> 7x = -98
<=> x = -98/7
<=> x = -14
ii) 5y - 4 = 2y - 25
<=>3y = -21
<=> y = -21/3
<=> y = -7
iii) 4(p + 3) = 36
<=> p + 3 = 36/4
<=> p + 3 = 9
<=> p = 9 - 3
<=> p = 6
iv) 2 (4f + 3) = 3 (2f + 6)
<=> 8f + 6 = 6f + 18
<=> 2f = 12
<=> f = 12/2
<=> f =6
Hope this helps!
