Complementary angles add up to 90 (there should be a right angle in the diagram)

x+20+x+10 needs to equal 90 where x=30

Left angle is measured 30+20=50 degrees

Angle on the right is measured 30+10=40 degrees

Which exponential function has an initial value of 2? f(x) = 2(3x) f(x) = 3(2x)

Sidana [21]

f(x) = 2(3x)
Exponential functions represent the initial value outside of the parentheses so if 2 is the initial value it has to be on the outside of the parentheses.
Exponential growth formula.
 $y=a(1+r)^{x}$
a represents the initial value.

.If the side of an equilateral triangle is 6cm, then the area of triangle is

Oksi-84 [34.3K]

Answer:

$9\sqrt{3}$ cm^2

Step-by-step explanation:

area of an equilateral triangle = $\frac{s^{2} \sqrt{3} }{4}$ (s = length of the side)

area = $\frac{6^{2}\sqrt{3} }{4}$

area = $\frac{36\sqrt{3} }{4}$

area = $9\sqrt{3}$ cm^2

The surface areas of two similar solids are 340 yd² and 1,158 yd². The volume of the larger solid is 1,712 yd³. What is the volu

ratelena [41]

The ratio of surface area is equal to the ratio of the square of the corresponding dimensions. And ratio of volumes of two solids is equal to the cube of the ratio of the corresponding dimensions .

We start with the relation between ratio of surface area and ratio of corresponding sides. That is

$\frac{340}{1158}=(\frac{x}{y} )^2$
