Answer:
the value of the angle k is 73° .
Step-by-step explanation:
Great question, it is always good to ask away and get rid of any doubts that you may be having.
Triangles have many important properties that are extremely helpful. One of the most important properties about all triangles is that the sum of all three interior angles sums up to be 180°. This being the case we can sum up the angles already given to us and subtract it from 180° in order to find the missing angle (k).
Finally, we can see that the value of the angle k is 73° .
I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

Given maria has in the pennies & quarters.
she has twice as many pennies as quarters.
find out the coins
let us assume the quarters are x
than the pennies are 2x.
Formula
value of the pennies + value of the quarters = total value of coins
1 quarters =$ 0.25
1 pennies = $0.01
Thus
0.25x + 0.01 (2x) = 2.43
0.27 x = 2.43
x = 9
2x = 18
i.e the number of quarters are 9 and the number of pennies are 18.
Hence proved

Answer:
240951.33km
Step-by-step explanation:
For this type of question first we need to draw the figure as shown in the attached file (Figure.1).
Looking at the figure, we can see that triangle ABC is formed by bisecting the angle 35 degree (i.e. if the angle is bisected, it will divide into two equal parts, so 35 degree will divide into two equal parts of 17.5 degree).
As the triangle ABC is a right triangle, so we can use the trigonometric ratios to find the diameter of the sun.
In the triangle ABC, perpendicular (opposite side to ) is BC and base (Adjacent side) is AC
=17.5 degree
AC=382100km
Putting the values, we get
Diameter=d=2*Radius
As BC is the distance from center of the sun, it is the radius, so we can find the diameter if we multiply it by 2.
Diameter of the sun=d=2*120475.66km
