In the right triangle above, a = 99 and c= 124. Find the value of b, rounded to the nearest tenth.

Murljashka [212]

Answer:

B= -40

Step-by-step explanation:

So a right triangle has to = 180

So we write the given, which 124+99

we are trying to get 180 so lets subtract that by the equation, 180-124+99

180-(124+99)

12+99=223

180-223

=-43

But in your case it has to be rounded to the nearest tenth

So the answer is -40

Determine if the segment lengths form a triangle. If so, would the triangle be acute, right, or obtuse? 4.1, 8.2, 12.2

goldfiish [28.3K]

Three line segments can form a triangle if the length of the longest segment is greater than the sum of the lengths of the shorter segments.

$4.1 + 8.2 \ \textgreater \ 12.2 \\
12.3 \ \textgreater \ 12.2 \\
true$
They can form a triangle.

Now if c is the length of the longest side and a and b are the lengths of the shorter sides, then:
- if $c^2=a^2+b^2$ , the triangle is right
- if $c^2\ \textless \ a^2+b^2$ , the triangle is acute
- if $c^2\ \textgreater \ a^2+b^2$ , the triangle is obtuse

$4.1^2+8.2^2=16.81+67.24=84.05 \\
12.2^2=148.84 \\ \\
148.84\ \textgreater \ 84.05$
The triangle is obtuse.

The answer is D.

tell whether the angles are adjacent or vertical then find the value of x. can someone help me please i need all the answers

dmitriy555 [2]

Answer:

3. adjacent; 49
4. adjacent; 71

5. verticle; 41

6. adjacent; 14

Step-by-step explanation:

ok basically if the angles are next to each other, then they're adjacent and if they're across from eachother they're verticle.

to find 3:

set both equations equal to each other and solve because verticle angles are equal

to find 4:

add the 2 equations together and set it equal to 180 because adjacent angles add up to equal either a complementary angle or supplementary depending on the problem
