The answer must be
since the triangular pyramid has 4 faces and each has an area of 30
we should multiply that by 4 , so :
Answer:
All Real Numbers
Step-by-step explanation:
Answer:
1. 10 6/7 2. 8/15
Step-by-step explanation:
1. 6 1/42 + 4 5/6
- First, let's combine the whole numbers. 6 + 4 = 10
- Now we are left with 1/42 + 5/6.
- To add or subtract, the dominators need to be the same. We need to find the least common multiple which here is 42.
1/42 + 5/6(7)
1/42 + 35/42
= 36/42
= 6/7
- All we have to do is combine both numbers.
10 6/7
2. 13/15 - 1/3(5)
13/15 - 5/15
8/15

We're suppose to measure the trigonometric values of the triangles and the values of indicates angles .For that,We need to know that,Sin θ = side opposite to angle θ / HypotenuseCos θ = side adjacent to angle θ / HypotenuseTan θ = side opposite to angle θ/side adjacent to angle θNow,In the first triangle,We're provided by,side opposite to angle θ =QR =24side adjacent to angle θ = PR = 10Hypotenuse = PQ = 26So,Sin P = 24/26Cos P = 10/26Tan P = 24/10m∠P = sin p° = 24/26m∠P= sin^-1(24/26)m∠P= 67.38 °In the second triangle,We're provided by,side opposite to angle θ =MO =9side adjacent to angle θ = NO = 40Hypotenuse = MN= 41So,Sin N= 9/41Cos N= 40/41Tan N= 9/40m∠N = sin N° = 9/41m∠N= sin^-1(9/41)m∠N= 12.68°In the third triangle,We're provided by,side opposite to angle θ =AC =15side adjacent to angle θ = AB = 8Hypotenuse = BC = 17So,Sin B = 15/17Cos B = 8/17Tan B = 15/8m∠B = sin p° = 15/17m∠B= sin^-1(15/17)m∠B= 61.93°In the fourth triangle,We're provided by,side opposite to angle θ =BC =8side adjacent to angle θ = AC = 6Hypotenuse = AB = 10So,Sin A = 8/10Cos A = 6/10Tan A = 8/6m∠A = sin p° = 8/10m∠A= sin^-1(8/10)m∠P= 53. °*53.13°
