Find the cosine of both angle A and angle B.
Svetach [21]
We know that

cos A=adjacent side angle A/hypotenuse
adjacent side angle A=24 units
hypotenuse=26 units

cos A=24/26-----> 12/13

cos B=adjacent side angle B/hypotenuse
adjacent side angle B=10 units
hypotenuse=26 units

cos B=10/26------> 5/13

the answers are
cos A=12/13
cos B=5/13

cot A=adjacent side angle A/opposite side angle A
adjacent side angle A=24 units
opposite side angle A=10 units
cot A=24/10------> cot A=12/5

cot B=adjacent side angle B/opposite side angle B
adjacent side angle B=10 units
opposite side angle B=24 units
cot B=10/24------> cot B=5/12

Compute: (4 + 9) − 3(6) ÷ 2 + 8
Vinil7 [7]
The answer is 12

Step 1. Perform the operations inside the parenthesis:
(4 + 9) − 3(6) ÷ 2 + 8 = 13 - 18 ÷ 2 + 8

Step 2. Division has advantage over subtraction and addition:
13 - 18 ÷ 2 + 8 = 13 - 9 + 8

Step 3. Subtract and add:
13 - 9 + 8 = 12
