Pls help i’m very confused

4x+12=y^2

Step-by-step explanation:

x = 90, y= 43

Step-by-step explanation:

At first it looks like you dont have enough information, but if you look at the overall (including both triangle) triangle, you can solve.

The sum of angles inside a triangle is 180, also due to congruency:

m∠B = m∠C = 47°

The triangle ABC

180 = 47 + 47 + y + y

180 = 94 + 2y; subtract 94 from both sides

86 = 2y; divide by 2

y = 43°;

Now use y=43° to solve for x°

x = 180 - m∠B - y°

x = 180 - 47 - 43

x = 90°

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.

step-by-step explanation:

it will be a cylinder. with a diameter of 8 and 4 single pieces high
