Answer:

Step-by-step explanation:

SAS = side-angle-side

This means that, in order to prove that the triangles are congruent, they must have two congruent sides with the angle between them to the same.

We know that sides AB, ED, AC, and DF are all congruent as they all have a single mark through them. From this, you can conclude that the triangles already share two sides. All we need now is the angles in between to be congruent. This means that angle A and angle D need to be congruent.

I hope this helps!

On Monday, Maggle ran n miles. On Tuesday, she ran 90% of the number of miles that she ran on Monday. On Wednesday, she ran 50%

Nimfa-mama [501]

Answer:

$Total = 2.35n$

Step-by-step explanation:

Given

Monday = n

Tuesday = 90% of Monday

Wednesday = 50% of Tuesday

Required

Determine the total miles

We have:

Tuesday = 90% of Monday

Substitute n for Monday

Tuesday = 90% of n

$Tuesday = 90\% * n$

Express percentage to decimal

$Tuesday = 0.90 * n$

$Tuesday = 0.90n$

We also have that:

Wednesday = 50% of Tuesday

Wednesday = 50% * Tuesday

Substitute 0.90n for Tuesday

$Wednesday = 50\% * 0.90n$

Express percentage to decimal

$Wednesday = 0.50 * 0.90n$

$Wednesday = 0.45n$

The total number of miles is:

$Total = Monday + Tuesday + Wednesday$

$Total = n + 0.90n + 0.45n$

$Total = 2.35n$

Find the value of x in the isosceles triangle below.

erastova [34]

Answer:

x = 64

Step-by-step explanation:

Remark

The markings on the triangle tell us that the sides are equal. There is no marking on the third side, so it is not equal to the other two. The important fact is the angles opposite equal sides are also equal. That means that the angle on the lower right is equal to x.

Equation

So you have two angles = to x.

x + x + 52 = 180 All triangles have interior angles of 180

2x + 52 = 180 Combine the like terms on the left.

<u> - 52 -52</u> Subtract 52 from both sides

2x = 128 Divide by 2

2x/2 = 128/2

x = 64
