Answer:

140°

Step-by-step explanation:

Three angle are labeled below the acre. The smallest angle is 3/8 as large as the 160 angle. Find the value of angle a

The value of the smallest angle is given as:

= 3/8 of the 160 angle

=3/8 × 160°

= 60°

The sum of the total angle = 360°

Hence:

360° = 60° + 160° + a

a = 360° - (60° + 160°)

a = 360° - 220°

a = 140°

Therefore, a = 140°

Vesna [10]

Answer:

The answer is "152 ft"

Step-by-step explanation:

Please find the attached file.

The area of the square (8 \times 5=40) can be found on the foot.

The area of the triangular front will then be calculated (6\times 4=\frac{24}{2} = 12).

Since each has two sides, 24+80=104.

Therefore the multiplying the area of the bottom square (6\times 8=48)by the number of cells to get 152.

1. what two things need to be true in order to add/subtract two radicals ?
Novay_Z [31]

Answer: 1. To add or subtract radicals, the indices and what is inside the radical (called the radicand) must be exactly the same. If the indices and radicands are the same, then add or subtract the terms in front of each like radical. If the indices or radicands are not the same, then you can not add or subtract the radicals.2.The index tells you how many of a kind you need to put together to be able to move that number or variable from inside the radical to outside the radical. For example, if the index is 2 (a square root), then you need two of a kind to move from inside the radical to outside the radical.3.When factoring a trinomial in the form x2 + bx + c, consider the following tips. Look at the c term first. o If the c term is a positive number, then the factors of c will both be positive or both be negative. In other words, r and s will have the same sign.
