$\bf{Hello!}$

The answer is 140°

Because we can use exterior angle property here

Exterior angle property : It states that exterior angle is the sum of two opposite interior angles

y = 120 + 20 = 140°

Answer:

140 degrees

Step-by-step explanation:

A triangle's sum of interior angles is 180.

120+20=140

180-140=40

So X= 40.

X and Y are supplementary, so they both add up to 180.

180-40=140

Therefore, Y=140.

Graph the exponential function g(x)= 3/5^x

givi [52]

Hello!

You put the numbers in for x

3/5^-2 = 2.777
3/5^-1 = 1.667
3/5^0 = 1
3/5^1 = 0.6
3/5^2 = 0.36

The points are (-2, 2.777), (-1, 1.667), (0, 1), (1, 0.6), (2, 0.36)

Hope this helps!

There are x number of students at helms. If the number of students increases by 7.8% each year, how many students will be there

vodomira [7]

There will be 1.078x students next year and equation is number of students in next year = x + 7.8% of x

<h3>Solution:</h3>

Given, There are "x" number of students at helms.

The number of students increases by 7.8% each year which means if there "x" number of students in present year, then the number of students in next year will be x + 7.8% of x

Number of students in next year = number of students in present year + increased number of students.

$\begin{array}{l}{\text { Number of students in next year }=x+7.8 \% \text { of } x} \\\\ {\text { Number of students in next year }=x\left(1+\frac{7.8}{100}\right)} \\\\ {\text { Number of students in next year }=x(1+0.078)=1.078 x}\end{array}$

Thus there will be 1.078x students in next year

The image shows a ray of light bending at the boundary of a glass block. According to a law of optics, = n, where n is a constan

Salsk061 [2.6K]

The law of optics applicable in this scenario is the Snell's Law which states that the ratio of the index of refraction of two media is equal to the ratio of the sine of the angle of reflection and sine of the angle of refraction. In equation form:
n₁ / n₂ = sin b / sin a
