Answer:
Largest angle is 94.22°
Explanation:
The sides of the triangle are given as 6 inches, 11 inches, 13 inches.
Now, we can find the respective interior angles of the triangle using cosine rule.
Thus, for the angle opposite 6 inches, let's label it A. Thus;
6² = 11² + 13² - 2(11 × 13)cos A
36 = 121 + 169 - 286cosA
36 = 290 - 286cos A
290 - 36 = 286cosA
cosA = 254/286
A = cos^(-1)0.8881
A = 27.36°
Similarly;
11² = 6² + 13² - 2(6 × 13)cos B
121 = 36 + 169 - 156cosB
121 = 205 - 156cos B
205 - 121 = 156cosB
cosB = 84/156
B = cos^(-1)0.5385
B = 57.42°
Sum of angles in a triangle is 180°
Thus;
C = 180 - (27.36 + 58.42)
C = 94.22°
Thus,largest angle is 94.22°
The sum of the internal angle of the triangle is 180 degrees. Then the measure of the largest angle is 95.22°.
What is trigonometry?Trigonometry deals with the relationship between the sides and angles of a triangle.
A wire is 30 inches long and is bent into a triangle with sides measuring 6 inches 11 inches 13 inches find the measure of the largest angle.
Then we know that the cosine rule is given as
[tex]\rm cos\ C = \dfrac{a^2+b^2-c^2}{2ab}[/tex]
Let the angle of the triangle be A, B, and C.
Then the first angle A will be
[tex]\begin{aligned} cos \ A &= \dfrac{6^2+11^2-13^2}{2*6*11}\\\\cos \ A&= \dfrac{36 + 121 - 169}{132}\\\\ A &= 95.22^o \end{aligned}[/tex]
And we know that the sum of the internal angle of the triangle is 180 degrees.
∠A + ∠B + ∠C = 180°
95.22° + ∠B + ∠C = 180°
∠B + ∠C = 84.78°

Explanation:
what is the Value of y in the equation
2/3y-7<1/2-13
Answer:
y < - 8 1/4
Explanation:
2/3y - 7 < 1/2 - 13
Collect like terms
2/3y < 1/2 - 13 + 7
2/3y < - 11/2
Divide both sides by 2/3
2/3y ÷ 2/3 < - 11/2 ÷ 2/3
2/3y * 3/2 < - 11 /2 * 3/2
y < - 11 /2 * 3/2
y < - 11 /2 * 3/2
y < - 33 / 4
y < - 8 1/4

Describe how mountains are formed at both convergent plate boundaries and divergent plate boundaries.
Answer:
Here's a non-copyrighted version of what the last person said :)
Mountain form at convergent plates boundaries, when the tectonic plates shove up against each other it forces the land to rise into mountainous forms as the said plates continue to clash.

Explanation:
A plane leaves Charlottetown, PEI at 12:00pm on Saturday, May 2nd. The destination is Yellowknife, NWT. The flight takes 17 hours. What is the date and time of your arrival in Yellowknife?
Answer: 5am on Sunday, May 3rd.
Explanation:
Plane left at 12pm and takes 17 hours.
Add 12 and 17:
= 12 + 17
= 29
There are 24 hours in a day. The number of hours into the next day is therefore:
= 29 - 24
= 5 hours
If the plan arrives 5 hours into the next day, that would mean that it arrived at 5am. Date of the next day is May 3rd, a Sunday.
