Answer:
68.3 degrees
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan I = opp side / adj side
tan I = sqrt(82) / sqrt(13)
tan I = sqrt(82/13)
Taking the inverse tan of each side
tan ^-1 ( tan I) = tan ^-1( sqrt(82/13))
I = 68.2892
Rounding to the nearest tenth
I = 68.3 degrees
C. The sun of the areas of its exterior surfaces is the correct answer.
Answer:
729
Step-by-step explanation:
I have not done this in some time so the terms may be a bit unconventional, but they work. The key to this is multiplying by -3.
1*(-3) = -3
-3*(-3) = 9
And so on.
1, -3, 9, -27, 81, -243, 729
Answer:
7. 84 feet
9. 12320 yd
11. 30 inches
12. 26400 ft
13. 19 ft
hope this helps
have a good day :)
Step-by-step explanation:
When you use the quadratic formula, you’re making the function equal to 0. So we know that the zeros happen when x equals 2 and 4. So let’s try to think of a trinomial that factors to (x - 2)(x - 4). You could do FOIL to get x^2 - 6x + 8.
Now if you want to show your work, plug everything into the quadratic formula. Due to limitations on a phone, ill just write it out.
-b plus and minus the square root of b squared minus 4 times a times c, alllll over 2 times a
