Answer:

$\displaystyle m\angle AED=32.5^\circ$

Step-by-step explanation:

Angles in a Circle

An exterior angle of a circle is an angle whose vertex is outside a circle and the sides of the angle are secants or tangents of the circle.

Segments AE and DE are secants of the given circle. They form an exterior angle called AED.

The measure of an exterior angle is equal to half the difference of the measure of their intercepted arcs.

Intercepted arcs in the given circle are AD=113° and BC=48°. The exterior angle is:

$\displaystyle m\angle AED=\frac{AD-BC}{2}$

$\displaystyle m\angle AED=\frac{113^\circ-48^\circ}{2}=\frac{65^\circ}{2}$

$\displaystyle m\angle AED=32.5^\circ$

2 other decimal forms of 6.7

Sergio039 [100]

Hi try

0.067

Explanation

6.7% = 0.067 in decimal form. Percent means 'per 100'. So, 6.7% means 6.7 per 100 or simply 6.7/100. If you divide 6.7 by 100, you'll get 0.067

Serena wants to solve the following system of equations in the most efficient way.

Marianna [84]

Answer:

Serina should have solved for x in the second equation because it has a coefficient of 1.

Step-by-step explanation:

we have

$2x+3y=18$ ----> equation A

$x+7y=31$ ---> equation B

we know that

To solve the system of equations in the most efficient way, solve for x equation B and then substitute the value of x in equation A

$x=31-7y$ ----> equation C

substitute equation C in equation A

$2(31-7y)+3y=18$

solve for y

$62-14y+3y=18\\11y=62-18\\11y=44\\y=4$

Find the value of x

substitute the value of y in the equation C

$x=31-7(4)=3$

The solution is (3,4)

therefore

Serina should have solved for x in the second equation because it has a coefficient of 1.

One angle of a right triangle measures 7º. What is the measure of the other acute angle?

ratelena [41]

Let other be x

Using angle sum property

$\\ \rm\Rrightarrow x+7+90=180$

$\\ \rm\Rrightarrow x+97=180$

$\\ \rm\Rrightarrow x=180-97$

$\\ \rm\Rrightarrow x=83°$

Y=-3x^2+6x+c; (1,0) find C

kogti [31]

Simplifying 3x2 + -6x + c = 0 Reorder the terms: c + -6x + 3x2 = 0 Solving c + -6x + 3x2 = 0 Solving for variable 'c'. Move all terms containing c to the left, all other terms to the right. Add '6x' to each side of the equation. c + -6x + 6x + 3x2 = 0 + 6x Combine like terms: -6x + 6x = 0 c + 0 + 3x2 = 0 + 6x c + 3x2 = 0 + 6x Remove the zero: c + 3x2 = 6x Add '-3x2' to each side of the equation. c + 3x2 + -3x2 = 6x + -3x2 Combine like terms: 3x2 + -3x2 = 0 c + 0 = 6x + -3x2 c = 6x + -3x2 Simplifying c = 6x + -3x2
