Answer:42.55
Step-by-step explanation:
Les get the big boi out of the way first. We see that it is 3.5 by 9 and if we multiply we get 31.5. Next left triangle 2 by 2 so four but divided by 2 is 2. God so many 2's. So total is 33.5 so far. Next triangle is 2 by 5 soo 10 divided by 2 is 5. total is 38.5. Last dude in the middle. We know one side is two so we have to subtract here from the triangles which gets u the other side of 2 so 4. Total is 42.5
Answer: 45.58 degrees
Step-by-step explanation:
Answer:
As per the given condition: Rodrigo has a ladder that is 13 ft long. The ladder is leaned against a vertical wall. The top of the ladder is 10.8 ft above the ground.
The Orientation of the ladder with the wall forms a right triangle.
The ladder length is the hypotenuse of the triangle,
the distance between the ladder at ground level and the base of the wall is the horizontal leg of the triangle,
and the height of the ladder is the vertical leg of the triangle.
⇒ Height of the ladder = 10.8 ft and hypotenuse = 13 ft
Using sine ratio formula;
Opposite side = height of the ladder = 10.8 ft and
Hypotenuse side = 13 ft.
then;
or
Simplify:
(nearest to tenth place)
Since, it is given that the angle the ladder makes with the ground needs to be 60 degree or less for safety purposes.
(a)
Yes, this ladder in a safe position.

(b)
You can see the diagram as shown below in the attachment.
Factor the following integer:
78
The last digit of 78 is 8, which means it is even. Therefore 78 is divisible by 2:
78 = 2 39:
78 = 2×39
39 is not divisible by 2 since 39 is odd and 2 is even:
78 = 2×39 (39 is not divisible by 2)
The sum of the digits of 39 is 3 + 9 = 12, which is divisible by 3. This means 39 is divisible by 3:
39 = 3 13:
78 = 2×3×13 (13 is not divisible by 2 since 39 is not)
The sum of the digits of 13 is 1 + 3 = 4, which is not divisible by 3. This means 13 is not divisible by 3:
78 = 2×3×13 (13 is not divisible by 2 or 3)
The last digit of 13 is not 5 or 0, which means 13 is not divisible by 5:
78 = 2×3×13 (13 is not divisible by 2, 3 or 5)
Divide 7 into 13:
| | 1
7 | 1 | 3
- | | 7
| | 6
13 is not divisible by 7:
78 = 2×3×13 (13 is not divisible by 2, 3, 5 or 7)
The alternating sum of the digits of 13 is 1 - 3 = -2, which is not divisible by 11. This means 13 is not divisible by 11:
78 = 2×3×13 (13 is not divisible by 2, 3, 5, 7 or 11)
No primes less than 13 divide into it. Therefore 13 is prime:
78 = 2×3×13
There is 1 copy of 2, 1 copy of 3 and 1 copy of 13 in the product:
Answer: 78 = 2×3×13
Answer:
Finding a tutor for mathematics? If that's the problem
Step-by-step explanation:
Try asking friends, family, close people in your family about mathematics. Maybe they have the same problem and somehow got over it by studying, asking questions, or they have a tutor, etc
Try using that same method that they used. If none of them have problems, ask your parents about that. They might be willing to sit down and teach you a little bit...
I have always had problems with math so I am sorry if it doesn't work out for you
