Which set of angles can form a triangle

Mathematics
1 answer:
Aleksandr [31]3 years ago
7 0

Answer:

  2 acute and 1 right

Step-by-step explanation:

The sum of angles of a triangle is always 180°.

Right angles are 90°, and obtuse angles are more than 90°. If each of the angles in the triangle is more than 0°, there obviously cannot be two angles that measure 90° or more. Just the sum of those two would be 180° or more, and that sum doesn't include the third angle.

So, any triangle can have at most one angle that is 90° or more (right or obtuse). The remaining two angles must be acute for the sum of angles to be 180°.

  2 acute and 1 right angle can form a triangle

I dont understand the problem

Answer:

equation of a line:

y = mx+c

1) find the gradient, m

m =  \frac{y2 - y1}{x2 - x1}

m =  \frac{ - 4 - ( - 4)}{ - 10 - 1}

m = 0

2) find y-intercept, c using coordinate (1,-4)

y = mx + c

-4 = 0(1) + c

c = -4

the equation of line:

y = mx+c

y = 0(x) + c

y = c

y = -4

The cost of a car, in dollars, t years after its purchase is $20,000 - $3,000t. Which statement is correct? please explain too.
xeze [42]
We start with 20,000. Every year t, we decrease 3,000. Thus, each year the car depreciates by 3,000 every year.

I need help!!! Brainliest for anyone who answers correctly on both!!!

Answer:

The first answer: 390m The second answer: x = 7; m<1 = 17; m<2 = 73

Step-by-step explanation:

First problem:

It's asking for the distance he walks by walking around a rectangular box which is the perimeter.

Two of the sides will have length 115m and two will have length 80m. So this perimeter is 115 + 115 + 80 + 80 = 390m.

Second problem:

Complementary angles add to 90 degrees. So m<1 and m<2 added together will equal 90

-4x +45 + 7x + 24 = 90

3x + 69 = 90

3x = 21

x= 7.

Plug back x into both m<1 and m<2 to find the measure of the angles.

m<1 = -4(7) + 45 = 45-28 = 17

m<2 = 7(7) + 24 = 49 + 24 = 73
