PYTHAGOREAN THEOREM IN 3D URGENT PLEASE PHOTO INSERTED
Andrews [41]

To find the length of the diagonal, we need to calculate the length of the base first and then use the value to calculate the diagonal since we are given the value of height of the triangle.

<h3>Pythagorean Theorem</h3>

This theorem is used to find the missing side of a right angle triangle given that we have the length of two sides.

To calculate the base of the triangle, let's use Pythagorean theorem here

x^2 = y^2 + z^2\\x^2 = 2^2 + 3^2\\x^2 = 4 + 9 \\x^2 = 13\\x = \sqrt{13} \\x = 3.61

Having the length of the base, let's consider the height of the triangle which is 6 and substitute the values.

d^2 = 6^2 + 3.61^2\\d^2 = 36 + 13.0321\\d^2 = 49.0321\\d = \sqrt{49.0321} \\d = 7.00

From the calculations above, the values of the triangle are

  • diagonal = 7
  • base = 3.61
  • height = 6

Snowcat [4.5K]

Answer:

1.5

Step-by-step explanation:

2 ft. / the number of sides for width (2) = 1 then 3 ft. / number of sides for length (2) = 1.5

1.5 x 1 = 1.5

A right angle intersects a line at point M. Which statement is true about angles 1 and 2? They are congruent. They are right ang
yulyashka [42]
The angle show with the yellow square has a measure of 90°.

Together with angles 1 and 2, they form a straight angle so we have:

∠1+∠2+90°=180°, 

subtracting 90° from both sides we have:

∠1+∠2=90°


If the sum of the measures of 2 angles is 90°, the angles are called complementary.

Since the sum of the measures of angles 1 and 2 is 90°, then these 2 angles are complementary.

Determine whether the given triangle has no solution, one solution or two solutions. Then solve the triangle. Round measures of
yuradex [85]

Answer:

The triangle has one solution. The remaining side c ≈ 4 and remaining angles B = 30°; C = 31°.

Option D is correct.

Step-by-step explanation:

if angle A is obtuse and if a > b then the triangle has one solution

We are given ∠ = 119° which is obtuse and side a= 7 and side b - 4 i.e 7>4 so, the triangle has one solution.

Finding remaining side c and ∠B and ∠C

Using Law of sines to find ∠B

a/sin A = b/sin B

7/sin 119° = 4/sin B

7 * sin B = 4 * sin 119

7*sin B = 4(0.874)

sin B = 3.496/7

B = sin^-1(0.4994)

B = 29.96 = 30°

We know that sum of angles of triangle = 180°

So, 180° = 119° + 30° +∠C

180° = 149° + ∠C

=> ∠C = 180° - 149°

∠C = 31°

Now finding c

b/sin B = c /sin C

4/Sin 30 = c/sin 31

4* sin 31 = c*sin 30

4*0.515 = c* 0.5

=> c =  4*0.515/0.5

c = 4.12 ≈ 4

So, Option D one solution; c ≈ 4; B = 30°; C = 31° is correct.
