Area of rectangle=> L•l= 8•5= 40 in²
Area of the triangle=> (b•h)/2= (8•3)/2= 24/2= 12 in²
Area of the shadowed surface is 40-12= 28 in²
It would be written as:
5.65 *10^-4
Remember, when writing scientific notation for a decimal, the power of 10 is always negative. In this case, since we're basically moving the decimal point for places to the right, the power of 10 is -4
Hope this helped! :)
90°-53°=37°
The whole angle is right angled
Answer:
x=10
Step-by-step explanation:
Step 1- <em>distribute</em>
2x-8=15
Step 2-<em> add 8 to 8 and 15 you will then cancel out the 8</em>
2x=23
Step 3- <em>divide 2 to cancel out the 2 </em>
you will then get 11.5
2(x-4)=15
2x-8=15
2x=23
x=11.5
