Area of all triangles : 10 x 12 = 120 120 divided by 2 = 60 then, 60 x 4 = 240

Area of the Square: 12 x 12 = 144

Surface Area of the Pyramid: 240 + 144 = 384 square millimeters!!

Hope This helps :)

\angle B=∠B=angle, B, equals ^\circ ∘ degrees Round your answer to the nearest hundredth.
Irina18 [472]

Answer:

<B is 53.13degrees

Step-by-step explanation:

Find the diagram attached

Given

Opposite side= 4 (side facing <B)

Adjacent side = 3

Required

<B

According to SOH CAH TOAS identity

tan theta = opp/adj

tan<B = 4/3

<B = arctan(4/3)

<B = arctan(1.3333)

<B = 53.13 degrees

Hence the angle <B is 53.13degrees based on the diagram

Flura [38]

Answer:

Angle, \theta=70.4^{\circ}

Step-by-step explanation:

We have, an A-frame house is 45 feet high and 32 feet wide. It is required to find the measure of the angle that the roof makes with the floor.

The attached figure shows the A frame. Let \theta is the angle that the roof makes with the floor. So,

\tan\theta=\dfrac{45}{16}\\\\\tan\theta=2.81\\\\\theta=\tan^{-1}(2.81)\\\\\theta=70.4^{\circ}

So, the angle of 70.4 degrees is the angle that the roof makes with the floor.
