Answer:

scalene triangle

Step-by-step explanation:

we know that

A <u><em>scalene triangle</em></u> is a triangle in which all three sides have different lengths. Also the angles of a scalene triangle have different measures.

In this problem we have a triangle in which all three sides have different lengths

$28\ mm\neq 53\ mm\neq 45\ mm$

therefore

Is a scalene triangle

Andrews [41]

Two angles are complementary when their sum is equal to 90°.

So, ( 2x + 39 ) + ( 7x - 21 ) = 90°

9x + 18° = 90°

x = 8°

Putting value of x in the angles given :

( 2x + 39 )° = 2(8°) + 39° = 55°.

( 7x - 21 )° = 7(8°) - 21° = 35°.

Therefore, the angles are 55° and 35°.

Hence, this is the required solution.

An archeologist discovered two artifacts buried beneath the ground. She found the first artifact at an elevation of -8:2/7 meter

8090 [49]

Answer:

Option D is the correct choice.

Step-by-step explanation:

We are provided angle of elevations of two artifacts buried beneath the ground and we are asked to find distance between these two elevations.

We will find distance between these elevations by taking the difference of two.

$35:\frac{4}{7}--8:\frac{2}{7}$

$35:\frac{4}{7}+8:\frac{2}{7}=43:\frac{6}{7}$

Since we know that distance is always positive so option A is incorrect.

Therefore, option D is the correct choice and distance between these two elevations is $43:\frac{6}{7}$ .

Answer:

40 degrees

Step-by-step explanation:

If all triangles add up to 180°, the 180-104-36=40, so the answer is 40°
