Area of a triangle = \frac{1}{2} · base x height
                     180 = \frac{1}{2} · base x 40
                     180 = 20 · base
                        9  = base

Pythagorean Theorem:
base² + height² = hypotenuse²
  9²     +    40²    = hypotenuse²
 81     +   1600   = hypotenuse²
      1681            = hypotenuse²
     √1681           = √hypotenuse²
         41            = hypotenuse

Answer: the length of the hypotenuse is 41 m

The cost of a customer's smartphone bill can be modeled by
Sergio039 [100]

Answer:

C = (g + 5)

Step-by-step explanation:

Given the cost of a customers smartphone bill,

C=10g+50

We are required to factor the polynomial.

First, determine the G.C.D of both terms

    The GCD of 10g and 50 is 10

Next, we divide each of the term by 10 and balance it by multiplying the expression by 10.

C = 10g + 50

 = 10 (10g / 10 + 50/10)

The cost polynomial factored is C=10(g+5).

The measure of arc LK is?
Oksi-84 [34.3K]

Answer:

Step-by-step explanation:

Because MK is a diameter, then angle L is a right angle. We already know that the measure of angle K is 50, so the measure of angle M has to be 40 because of the triangle angle-sum theorem. The rule for inscribed angles and the arcs they cut off is that the angle is half the measure of its intercepted arc or, likewise, the arc is twice the measure of the angle that cuts it off. Since arc LK is across from angle M and is cut off by angle M, then arc LK is twice the measure of angle M, and is 80. That's the same reason why angle L is 90; arc MK is a semi-circle, with a degree measure of 180, and angle L is half of that.

Arc LK = 80

Diano4ka-milaya [45]

Step-by-step explanation:

part A:

Area_{_{surface}}=3.14*(3*5+3^2);

part B:

Area_{_{surface}}=3.14*(15+9)=3.14*24=75.36[units^2].

Write a paragraph proof.
worty [1.4K]
It is given that line segment BC is congruent to line segment EC and that line segment AC is congruent to DC. Because of the vertical angles theorem, angle BCA is equal to angle DCE. Therefore, triangles CBA AND DEC are congruent by SAS. Using CPCTC, BA is equal to ED.
