ICE Princess25 [194]2 years ago
3 0

Answer:

60°

Step-by-step explanation:

Total angle measurement for a triangle is 180°

Equilateral triangle measures 60 on all angles. (60 + 60 + 60 = 180°)

This triangle is equilateral so it's angle is 60°.

Why is it equilateral? Because all sides of the triangle are equal (10 on all sides).

Hope this helps

Write an equation for the function
Mila [183]

Answer:

  m(u) = -0.25(u +2)² +1    or    -0.25u² -u

Step-by-step explanation:

The equation is fairly easily written in vertex form, as the vertex point is on a grid line intersection at (-2, 1). The parabola opens downward, so the scale factor is negative.

The vertical change from the vertex is only a fraction of a unit when u differs from the vertex by 1. It is 1 unit when u differs from the vertex by 2, so the magnitude of the vertical scale factor is 1/2² = 1/4.

Our equation will be of the form ...

  m(u) = (vertical scale factor)(u - (horizontal vertex location))² + (vertical vertex location)

For this graph, the equation is ...

  m(u) = -0.25(u +2)² +1

or, simplifying, we get ...

  m(u) = -0.25u² -u

Peter leaves his house and walks 15 meters south, then turns east and walks another 15 meters. How far is he from his house? Rou
Varvara68 [4.7K]
When Peter does this, he is creating two sides of a right-angle triangle. The distance from his house to that point will be the hypotenuse of the triangle thus, to work out the length of the hypotenuse, we have to use Pythagoras Theorem! So:

a² + b² = c²
15² + 15² = c²
225 + 225 = c²
450 = c²
15√2 = c
21.21320344 = c

So, this rounded to the nearest tenth would be:

21.2 meters !

Graph the system of equations on your graph paper to answer the question. {y=−3x+9y=−x−5 What is the solution for the system of
marysya [2.9K]

y=−3x+9 slope of this equation is -3 and y-intercept is 9

Plot the y -intercept first which is 9 and mark the points using the slope which is -3. Join the points. So blue line in the graph is y = -3x+9

y=−x−5 slope of this equation is -1 and y intercept is -5

Plot the y -intercept first which is -5 and mark the points using the slope which is -1 . Join the points. So pink line in the graph is y = -x-5

The intersection point of these two lines gives you the solution.

The coordinates of point of intersection (7,-12)
