Hello!
As you cans see, the angle is a right angle, which measures 90°. One of the angles measure 35°
90 - 35 = 55
That means 5x = 55°
Divide both sides by 5
![\frac{5x}{5} = \frac{55}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B5x%7D%7B5%7D%20%3D%20%20%5Cfrac%7B55%7D%7B5%7D%20)
Answer:
Since stress is greater than ultimate strength, the wire will break.
Step-by-step explanation:
The titanium wire is experimenting an axial load. Ultimate strength equals
. The wire shall break if and only if stress is at least equal to ultimate strength. The equation for axial stress (
), measured in pascals, in the wire with circular cross-section is:
(1)
Where:
- Axial force, measured in newtons.
- Cross-section diameter, measured in meters.
Please notice that axial force is the weight of the man hanging from wire.
If we know that
and
, then the axial stress experimented by the titanium wire is:
![\sigma = \frac{4\cdot (800\,N)}{\pi\cdot (0.002\,m)^{2}}](https://tex.z-dn.net/?f=%5Csigma%20%3D%20%5Cfrac%7B4%5Ccdot%20%28800%5C%2CN%29%7D%7B%5Cpi%5Ccdot%20%280.002%5C%2Cm%29%5E%7B2%7D%7D)
![\sigma \approx 2.546\times 10^{8}\,Pa](https://tex.z-dn.net/?f=%5Csigma%20%5Capprox%202.546%5Ctimes%2010%5E%7B8%7D%5C%2CPa)
Since stress is greater than ultimate strength, the wire will break.

In the attached diagram you can see Place Value Chart that is used to help understand the value of each digit based on the place or position.
For the number 756:
- 7 has a value of 7 hundreds, or 700;
- 5 has a value of 5 tens, or 50;
- 6 has a value of 6 ones, or 6.
Answer: 5 has a value of 5 tens, or 50
