pav-90 [236]3 years ago
8 0

Answer: A: 180= 90+4x+x

B: x=18

Step-by-step explanation:

1. Every triangle has a length of 180

2. So all the measurements combined would equal 180

3. So write the equation 180=90+4x+x

4. Let‘s simplfy, 180=90+5x

5. Subtract 90 from each side, 90=5x

6. Divide each side by 5, 18=x.

7. Double check our work! 90+(4*15)+18=180

35 km<br> 21 km<br> b<br> What is the length of the missing leg?<br> b =<br> kilometers
marta [7]

Answer:

28 km

Step-by-step explanation:

One leg = 35 km

Second leg = 21 km

We need to find the length of the missing leg. Using Pythagoras theorem, we  can find it.

Hypotenuse² = base² + perpendicular²

x=\sqrt{35^{2}-21^{2}}\\\\x=28\ km

So, the length of the missing leg is equal to 28 km.
