Well, to get the surface area, you do length x width x height. <span>Multiply the side length of the base by the slant height and divide by two. Then, multiply by 4. This will give you the lateral </span>surface area<span> of the </span>pyramid<span>.</span>

Answer:
yes
Step-by-step explanation:
When distance and time are both zero at once, and speed is constant, then distance and time are proportional:
distance = speed × time
The constant of proportionality is the (constant) speed.
Answer:
the long diagonal d=15.49 ( rounded to the nearest hundredth)
the shortest d=√136-120(cos 30)=5.663 ( rounded to the nearest hundredth)
Step-by-step explanation:
Area=height * base
30=h*6
h=30/6=5 cm
height=asinФ
sinФ=5/10=1/2 (Ф=30)
alternate angle=180
180-30=150 degrees
diagonal²=a^2+b^2-2abcos150
d²=10²+6²-2(10)(6)(-√3/2)
d=√136+60(√3)
the long diagonal d=15.49 ( rounded to the nearest hundredth)
the shortest d=√136-120(cos30)=5.663
<h2>
Answer: 55 degrees</h2>
Step-by-step explanation:
Every triangle has 3 sides and 3 interior angles whose measures sum to 180 degrees. For example, a triangle with angles
,
and
:
![\theta+\alpha+\beta=180\º](https://tex.z-dn.net/?f=%5Ctheta%2B%5Calpha%2B%5Cbeta%3D180%5C%C2%BA)
Following this rule, we will apply it to the angles XYZ, YXZ and the unknown XZY:
![XYZ+YXZ+XZY=180\º](https://tex.z-dn.net/?f=XYZ%2BYXZ%2BXZY%3D180%5C%C2%BA)
![50\º+75\º+XZY=180\º](https://tex.z-dn.net/?f=50%5C%C2%BA%2B75%5C%C2%BA%2BXZY%3D180%5C%C2%BA)
![XZY=180\º-50\º-75\º](https://tex.z-dn.net/?f=XZY%3D180%5C%C2%BA-50%5C%C2%BA-75%5C%C2%BA)
Finally:
![XZY=55\º](https://tex.z-dn.net/?f=XZY%3D55%5C%C2%BA)
