The surface area of the triangular pyramid shown is 94.6 in²
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
The surface area of the regular pyramid is given as:
Surface area = 3(0.5 * 4.3 * 13) + (0.5 * 4.3 * 5) = 94.6 in²
The surface area of the triangular pyramid shown is 94.6 in²

Answer:
125
Step-by-step explanation:
6 and 7 are on a straight line (180 degrees)
Angle 2 is equal to Angle 6
Therefore 180 - Angle 6 = Angle 7
180 - 55 = 125
30:2...this is the ratio in decimal form.
The result of this ratio is 15.
Remember it can also be written as a fraction too--> 30/2
This question uses trig
sin(55) = height/195
Therefore, height = 195sin(55) meters (just plug in calculator)
