Answer:

\boxed{\mathrm{A}}

Step-by-step explanation:

An obtuse triangle is a triangle with one obtuse angle and two acute angles.

An obtuse angle is an angle greater than 90 degrees.

An acute angle is an angle less than 90 degrees.

Angle <em>C</em> is an obtuse angle, it is greater than a right angle or 90 degrees.

Angles <em>B</em> and <em>A</em> are acute angles, they are less than a right angle or 90 degrees.

Which equation can be used to find the value of x?
Dafna11 [192]

Answer:

C

Step-by-step explanation:

We know every triangle equals 180 so were just going to take 180 - 42 = 138 then were going to do 138 - 67 = 71  we can check our work by doing

42 + 67+ 71 = 180. We also know 67 + 42 = 109.

Lets look at our answers;

A. 109 = 180 + x  When solved it gave me; x = -71. We got a positive 71 so this is incorrect.

B. x + 42 = 67   When solved it gave me;  x = 25, which is incorrect.

C. x = 180 - 109 When solved it gave me; x = 71

D. 42 + 67 - x = 180 When solved it gave me; x =  - 71

Therefore the answer is C.

Please help solve for x
Ludmilka [50]

Answer:

8.49

Step-by-step explanation:

there is a little formula related to the famous formula of Pythagoras.

it says that the height of a triangle is the square root of the product of both segments of the baseline (the segments the height splits the baseline into).

so, x is actuality the height of the triangle.

x = sqrt(3×24) = sqrt(72) = 8.49
