Find the missing angles

Mathematics
1 answer:
Elina [12.6K]2 years ago
4 0

Answer:

z=116 (opposite angles are equal)

y=180-(116+27)=37(angles in a triangle sum up to 180)

x:

(z) + (27+x) =180(interior angles on same side are supplementary

116 + 27+ x =180

x= 37

gayaneshka [121]

Answer:

It's not possible to reach a conclusion about who will vote candidate Taylor because this is a random sample and not a population census or experiment.

Step-by-step explanation:

It is impossible to reach a conclusion about the proportion of all likely voters who plan to vote for candidate Taylor because the 1,000 likely voters in the sample represent only a small fraction of all likely voters in a large city.

3/5 of a number decreased by one is 23. What is the number?
garri49 [273]
You can set up an equation based off of the information given:

x represents the unknown number

3/5x - 1 = 23

add 1 to both sides to isolate the 3/5x

3/5x = 24

divide both sides by 3/5 to solve for x

x = 120/3

120/3 can be simplified into 40

Final answer: x = 40

Find the total surface area of this cone. Round to the nearest tenth.
leva [86]

Step-by-step explanation:

for given cone:

h = 3 ft, r = 3 ft

Let l be the Slant height of cone.

\therefore \: l =  \sqrt{ {h}^{2}  +  {r}^{2} }  \\  =  \sqrt{ {3}^{2} +  {3}^{2}  }  \\  =  \sqrt{9 + 9}  \\  =  \sqrt{2 \times 9}  \\   \therefore \: l= 3 \sqrt{2}  \: ft \\  \\ total \: surface \: area \: of \: cone \\  = \pi \: r(l + r) \\  = 3.14 \times 3(3 \sqrt{2}  + 3) \\  = 9.42 \times 3( \sqrt{2}  + 1) \\  = 28.26 \times (1.414 + 1) \\  = 28.26 \times 2.414 \\  = 68.21964 \\  \approx \: 68.2 \:  {ft}^{2}

Answer:

H

Step-by-step explanation:

use slope of -2/3 and point (-4.5, 10) as input into the slope-intercept form of a line, which is y = mx + b

10 = -2/3(-9/2) + b

10 = 3 + b

7 = b

y = -2/3x + 7
