A triangle can have at most ________ right angle.
andrey2020 [161]
A triangle can only have at most one right angle.

Here's a proof that shows why this is so:

We know that the sum of all interior angles of a triangle must add up to 180.
Let's say the interior angles are A, B, and C

A + B + C = 180

Let's show that having two right angles is impossible

Let A = B = 90

90 + 90 + C = 180

180 + C = 180

Subtract 180 from both sides

C = 0

We cannot have an angle with 0 degrees in a triangle. Thus, it is impossible to have 2 right angles in a triangle.

Let's try to show that it's impossible to have 3 right angles

Let A = B = C = 90

90 + 90 + 90 = 180 ?

270 ≠ 180

Thus it's impossible to have 3 right angles as well.

Let's show that is possible to have 1 right angle

Let A = 90

90 + B + C = 180

Subtract both sides by 90

B + C = 90

There are values of B and C that will make this true. Thus, a triangle can have at most one right angle.

Have an awesome day! :)

John’s bank account increased in value from last year to those year by 8% to $250. If the account increases by the same percenta
inessss [21]

Answer:

$270

Step-by-step explanation:

We are given;

  • The rate of increase is 8%
  • The new amount is $250

We need to determine the value in the next year with the same rate of increase;

Therefore;

250% = 100%

New amount = 100 + 8 = 108%

Therefore;

New amount = (250 × 108)÷ 100

                      = $270

Therefore, the value in the next year is $270
