To find the surface area, you need to do the following:
A side of the figure is a trapezoid, so you should do 13+5x7 (since there are 2 of the same sides there is no need to divide by two.) and it should equal 126. To find the area of the top of the figure, you need to do 5x2 which equals 10. The area of the bottom of the figure is 26 (13x2), then do 2x3x2 to get the sides on the left and right of the figure. After all of this, add them together. (126+10+26+12=174.)
The surface area should be 174mm.
Answer:
142.932
Step-by-step explanation:
given that in triangle ABC, AC =24
Angle A = 30 and Angle B =45
If we draw altitude from C, we get
h = 24sin 30 = 12
Since BC = h (45, 45,90 triangle)
BC=12
By sine formula for triangle
Area of triangle
=

Answer:
Option D
Y=2.6x
Step-by-step explanation:
When y=10.4 and x=4, these two can be related by the equation
10.4=4x
Making x the subject of the formula then x=10.4/4=2.6
Relating x and y then we have the equation
Y=2.6x
For example, when x is 4 then y=2.6x=2.6(4)=10.4 as given in the question. Therefore, the right option is D
Y=2.6x
