Find vale of x ASSAP

Mathematics
2 answers:
Blizzard [7]4 years ago
7 0

Answer:

x = 127°

Step-by-step explanation:

in each triangle, the value of each exterior angle is equal to the sum of its two non-adjacent interior angles..

47° + 80° = 127°

or

the third angle in the triangle:

180° - (47° + 80°) = 53°

exterior angle:

180° - 53° = 127°

Answer: 127°

Step-by-step explanation: In the triangle shown, angle <em>x</em> is an exterior angle because it's formed when one side of the triangle is extended. To find the value of <em>x</em>, we use the exterior angle theorem.

This tells us that the measure of an exterior angle of a triangle is equal to the sum of the measures of the remote interior angles. The remote interior angles are all the angles except for <em>x</em>.

So all we need to do is add 47 + 80 and we get a sum of 127.

This means that <em>x</em> is equal to<em> 127°</em>.

What is the sum of the first 39 positive odd numbers?
liq [111]
1-39 ODD:
1,3,5,7,9,11,13,15,17,19,21,23,25,27,29,31,33,35,37,39
Now you'd add them all up.
1+3+5+7+9 = 25
11+13+15+17+19 = 75
21+23+25+27+29 = 125
31+33+35+37+39 = 175
Add the totals:
25+75+125+175
The answer would be 400.

Type SSS, SAS, ASA, AAS, or HL to justify why AABC = ADEF.<br><br> AC FD and AB = DE
bezimeni [28]

The theorem that justifies why triangles ABC and DEF are congruent is: HL.

<h3>What is the Hypotenuse-Leg Congruence Theorem (HL)?</h3>

The hypotenuse-leg congruence theorem (HL) states that if two triangles that are right triangles have a pair of congruent hypotenuse and a pair of corresponding congruent legs, then both right triangles are proven to be congruent to each other. This means both right triangles are have the same shape and size.

Given that:

angle ABC = angle DEF = 90° (congruent right angles, this means both triangles are right triangles)

AC = FD (a pair of congruent hypotenuse)

AB = DE (a pair of congruent legs)

Thus, we can conclude that since triangle ABC and triangle DEF have a pair of congruent hypotenuses and a pair of congruent legs, therefore, the two right triangles, triangle ABC and triangle DEF are congruent to each other by the HL congruent theorem.

Thus, the theorem that justifies why both triangles are congruent is: HL.

Brooke decided to ride her bike from her home to visit her friend Adam. Two miles away from home, her bike got a flat tire and s
Naddika [18.5K]

Answer:

8 miles

Step-by-step explanation:

I'm going to assume the question said that she "couldn't" repair the tire and was forced to walk back home, that makes more sense.

With that in mind:

She rode her bike 2 miles.

She walked 4 miles on the way there, and 6 miles on the way back.

You can deduce that it was a 6 mile walk back because of the 2 mile bike ride, then the 4 mile walk that it took to get there.

All in all that rounds out to 10 mile walking, and 2 mile biking. That is 8 miles more walking than biking.
