That would be zero.

Obtuse means more than 90 degrees. A triangle's angles add up to 180 degrees so can't have two obtuse angles.

Answer:

Perimeter of triangle J= 18.0 units (3 s.f.)

Perimeter of triangle K= 19.0 units (3 s.f.)

Step-by-step explanation:

The length of each side of the triangle can be found using the distance formula below:

$\boxed{d= \sqrt{(y1- y2)^{2} + (x1 - x2)^{2} } }$

Please see the attached pictures for full solution.

Expression: (5−2)2+23×4 Step 1: (3)2+23×4 Step 2: 9+23×4 Step 3: 9+9×4 Step 4: 9+36 Step 5: 45 Emily made a mistake. Which step

Levart [38]

Answer:

Step 3

Step-by-step explanation:

Given

$(5 - 2)^ 2 + 23 * 4$

Required:

Determine the first step where she made mistake

Her Step 1:

$(3)^ 2 + 23 * 4$ --- This is correct because she solved the bracket first

Her Step 2:

$9 + 23 * 4$ --- This is correct because she solved 3^2 as 9

Her Step 3:

$9 + 9 * 4$ --- This is incorrect because 23 * 4 is not equivalent to 9 * 4

Hence, her first mistake is in step 3.

The correct expression would have been

$9 + 92$

Then

$= 101$
