Answer:

angle CDE is 10 degree

Step-by-step explanation:

As angle C is 90

Angle E is equal to angle B which is 80 (180-100)

so 90+80+X=180

X=180-170

X=10

Interest earned: ? Principal: $800 Interest rate: 6.5% Time: 2 years

Lubov Fominskaja [6]

So lets remember the formula for interest first.
#lightbulb
here it is A = P(1 + rt)
all we really have to do is plug in our rates, principles, and time into equation.
P = $800
t = 2 years
r = 6.5% or as a decimal 0.065
now lets look at our new equation that finally has numbers in it

A = 800[1 +(0.065)(2)] first lets take care of the 0.065 and 2 by multiplying them together. thus our new equation.
A = 800(1+ 0.13) then we add the 1 to the 0.13 and get 1.13
800(1.13) from here we just multiply and that equals 904
since we are looking for what is earned we take 904 and subtract 800 to get that answer. Here is the math.

904 - 800 = 104
he made 104 dollars in 2 years!
hope this is right.
have a good one:)

What is the value of y−5x−3for x = 2 and y = -4

arlik [135]

Answer

-17

Explanation

y−5x−3 for x = 2 and y = -4

We solve this question by substituting the values of y and x.

y−5x−3 = -4 - 5(2) - 3

= -4 - 10 -3

= -14 - 3

= -17

Which equation listed below, when solved, shows how to find the circumference of a circle if the diameter is 6 inches? Use 3.14

siniylev [52]

The pertinent formula for the circumference of a circle with diameter d is

C =pi*d.

Thus, if the dia. is 6 inches, the circumf. is C = 6pi inches. Alternatively, if we let pi = 3.14, the circumf. is C = 6*3.14 (answer A).

4) (Assume AR is tangent) Given: AR 12 SR - 7.7 Find: cs (Round to nearest tenth.)

andreev551 [17]

The length of CS is 11.0

Explanation:

Given that the length of the tangent AR is 12

The length of SR is 7.7

To find: The length of CS

The tangent secant theorem states that "if a tangent and a secant are drawn from an external point to a circle, then the square of the measure of the tangent is equal to the product of the measures of the secant’s external part and the entire secant."

Applying the tangent secant theorem, we have,

$AR^2=SR\times RC$
