Given that lines m and n are parallel and m<60, find the measures of the remaining angles m<3=?
grigory [225]

When you have two parallel lines being cut by a transversal, you can use the next statements for the angles:

The measurement of the angles in green is the same (are congruents)

The measurement of the angles in blue is the same (are congruents)

An angle in green is a complementary angle with an angle in blue. (The addition of the two angles has to be 180º)

You know that:

m\angle2=60º

As the angle 3 is congruent with angle 2:

m\angle3=60º

An AISI 1040 cold-drawn steel tube has an OD 5 50 mm and wall thickness 6 mm. What maximum external pressure can this tube withs
lukranit [14]

Answer:

82.79MPa

Step-by-step explanation:

Minimum yield strength for AISI 1040 cold drawn steel as obtained from literature, Sᵧ = 490 MPa

Given, outer radius, r₀ = 25mm = 0.025m, thickness = 6mm = 0.006m, internal radius, rᵢ = 19mm = 0.019m,

Largest allowable stress = 0.8(-490) = -392 MPa (minus sign because of compressive nature of the stress)

The tangential stress, σₜ = - ((r₀²p₀)/(r₀² - rᵢ²))(1 + (rᵢ²/r²))

But the maximum tangential stress will occur on the internal diameter of the tube, where r = rᵢ

σₜₘₐₓ = -2(r₀²p₀)/(r₀² - rᵢ²)

p₀ = - σₜₘₐₓ(r₀² - rᵢ²)/2(r₀²) = -392(0.025² - 0.019²)/2(0.025²) = 82.79 MPa.

Hope this helps!!

Dwayne hikes 60 miles in 3 days. At that rate, how many days does it take him to hike a total of 240 miles
NNADVOKAT [17]

12 days. 60 is a quarter of 240. So, multiply 60 by 4 to get 240.

Which polygon has an interior angle sum of 1260°?
Liono4ka [1.6K]

Answer:

Step-by-step explanation:

Sum of interior angle of any polygon =(n-2) × 180°where n represents the number of sides in any polygon.

Or 1260 =(n-2)x180

Dividing both sides by 180:

7=n-2

Adding both sides by 2 we have :

n=9.

Hence a nanogon will have the sum of interior angles as 1260°.
