Answer:

10 degrees

Step-by-step explanation:

The answer is 10 degrees because the angle is complementary which means its going to be 90 degrees so all you have to do to find the answer is add 50+30 and boom 10 degrees

<h3>Answer:   80</h3>

====================================================

Explanation:

There are probably many approaches here, but one way to do this is to extend segment DO to form a line. Check out the diagram below. This line is in red.

The goal is to have this line extend to intersect with line AB. Let's call this intersection point E.

In that diagram, I've marked the variable y as angle EOB. Notice that angles BEO and CDO are congruent alternate interior angles (since lines AB and CD are parallel). So that's where that extra 30 degree angle comes from.

Focus on triangle EOB. The three angles of any triangle always add to 180

E+O+B = 180

30+y+50 = 180

y+80 = 180

y = 180-80

y = 100

The last step is to solve the equation below for x

x+y = 180

x+100 = 180

x = 180-100

x = 80

This works because angles x and y are supplementary. They form a straight angle.

Answer:  A & C

<u>Step-by-step explanation:</u>

HL is Hypotenuse-Leg

A) the hypotenuse from ΔABC ≡ the hypotenuse from ΔFGH

   a leg from ΔABC ≡ a leg from ΔFGH

   Therefore HL Congruency Theorem can be used to prove ΔABC ≡ ΔFGH

B) a leg from ΔABC ≡ a leg from ΔFGH

   the other leg from ΔABC ≡ the other leg from ΔFGH

   Therefore LL (not HL) Congruency Theorem can be used.

C) the hypotenuse from ΔABC ≡ the hypotenuse from ΔFGH

   at least one leg from ΔABC ≡ at least one leg from ΔFGH

   Therefore HL Congruency Theorem can be used to prove ΔABC ≡ ΔFGH

D) an angle from ΔABC ≡ an angle from ΔFGH

   the other angle from ΔABC ≡ the other angle from ΔFGH

   AA cannot be used for congruence.

Which is different? Find "both" answers.​
zimovet [89]

Answer : The different is, find BC - AC and find AC + CB, find AB and find CA + BC are same.

Step-by-step explanation :

As see that, AB is a line segment in which point C is represented in between the line.

As we are given that:

AC = 3

CB = 7

So,

AC + CB = 3 + 7 = 10

Similarly,

CA + BC = 3 + 7 = 10

Similarly,

AB = AC + CB = 3 + 7 = 10

But,

BC - AC = 7 - 3 = 4

From this we conclude that, find AC + CB, find AB and find CA + BC are same things while find BC - AC is a different thing.

Hence, the different is, find BC - AC and find AC + CB, find AB and find CA + BC are same.
