Using the figure below, find the measure of z ( just enter in the number for your answer don’t worry about the degree symbol or

belka [17]

Answer:

z = 29°

Step-by-step explanation:

We know that the 3 angles in a triangle always add up to 180°. So for triangle ABC, angle A = 59° (given), and angle B = 43° + 49° = 92° (given).

angle A + angle B + angle C = 180°

59° + 92° + z = 180°

151° + z = 180°

Subtract 151° from both sides of the equation

z = 180° -151°

z = 29°

PLEASE HELP!

makvit [3.9K]

Answer:

Step-by-step explanation:

diameter = 12 cm

r = 12 ÷ 2 = 6 cm

h = 6 cm

$\sf \boxed{\text{\bf Volume of cone = $\dfrac{1}{3} \pi r^2h$ }}$

$\sf = \dfrac{1}{3}*3.14*6*6*6\\\\ = 226.08 \ cm^3$

To find the surface area, we need to find the slant 'l'

$\sf l = \sqrt{h^2+r^2}\\\\ =\sqrt{6^2+6^2}\\\\ = \sqrt{36+36}\\\\ =\sqrt{72}\\\\= 8.49 \ cm$

$\sf \boxed{\text{\bf Total surface area of cone = $\pi r(r+l)$}}$

= 3.14 * 6 * (6 + 8.49)

= 3.14 * 6 * 14.49

= 273 cm²

Using the rules for special cases, what is the result of?

Arlecino [84]

Answer:

C) 4x^2 -8x +4[/tex]

Step-by-step explanation:

(-2x+2)^2

we apply (a+b)^2 formula

$(a+b)^2 = a^2 + 2ab +b^2$

a= -2x and b= 2

Replace 'a' with -2x and 'b' with 2

$(-2x+2)^2 = (-2x)^2 + 2(-2x)(2) +2^2$

(-2x)^2 is 4x^2

$(-2x+2)^2 = 4x^2 -8x +4$

option C is the answer
