Since the only two corresponding side you have are 10 units and 4 units, you can divide these two numbers to get the scale factor.

10÷4=2.5

next you find the sides corresponding to X Y and Z and if it is on the bigger figure you divide, if it is on the smaller side you multiply

X corresponds with 5 (so ×2.5)
Y corresponds with 8 (÷2.5)
Z corresponds with 10 (÷2.5)

final answer is X=12.5 Y=3.2 Z=4

I try to explain the question and give the answer, I hope this helps!

The area of the base of the regular quadrilateral pyramid is 36 cm2 and the area of a lateral face is 48 cm2. Find: Surface area
Thepotemich [5.8K]
Surface Area (SA) = Base Area (Ab) + Lateral Area (AL)

Base Area = 36cm^2
Lateral Face Area = 48cm^2

*If this is a quadrilateral pyramid, then it has 4 lateral faces, so just multiply the "one" lateral face by 4.

Lateral Area (AL) = 4 x Lateral Face Area
-> AL = 4 x 48 = 192 cm^2

So:

SA = Ab + AL
-> SA = 36 + 192
-> Surface Area = 228 cm^2

Which is a measure of the missing angle in this triangle?
Taya2010 [7]
<h2><u>Given</u>:-</h2>

Let us assume the three angles to be angle 1, angle 2 and angle 3.

Angle 1 = 35°

Angle 2 = 120°

<h2><u>To</u> <u>find</u>:-</h2>

Angle 3.

<h2><u>Solution</u>:-</h2>

{\boxed{\mathcal{\red{The \:measure\:of\:the\:missing\:angle\:is\:25°. \:✅}}}}

<h2><u>Step</u>-<u>by</u>-<u>step</u> <u>explanation</u>:-</h2>

We know that,

\sf\pink{Sum\:of\:angles\:of\:a\:triangle\:=\:180°}

➪ ∠ 1 + ∠ 2 + ∠ 3 = 180°

➪ 35° + 120° + ∠ 3 = 180°

➪ 155° + ∠ 3 = 180°

➪ ∠ 3 = 180° - 155°

➪ ∠ 3 = 25°

\sf\red{Therefore, \:the\: measure \:of \:∠\: 3\: is \:25°.}

<h2><u>To</u> <u>verify</u>:-</h2>

∠ 1 + ∠ 2 + ∠ 3 = 180°

✒ 35° + 120° + 25° = 180°

✒ 180° = 180°

✒ L. H. S. = R. H. S.

\boxed{Hence\:verified.}
