This is not possible. A triangle is either acute (all angles less than 90 degrees), right (one 90 degree angle), or obtuse (an angle with more than 90 degrees). There can not be an "acute right triangle."

Solve the equation 5n+7=21

Simora [160]

Answer:

Hi there, I believe the answer to this equation is: 2.8

Step-by-step explanation:

Subtract 7 on both sides so

5n+7=21-7

you are left with 5n=14 you need to get n by itself so divide 5 on both sides.

5n/5 = 14/5

n=2.8

Hope this is correct :)

Have a great day

28.)Find the value of x.320(3x-10°A.) x = 22.67B.) x = 34.67C.) x = 21.6D.) x = 24.25

katen-ka-za [31]

Since the big triangle is an isosceles one, we conclude that the angles of the left triangle are: 32, 90 and 3x-10. Sinche the sum of this angles have to be 180° we have:

$(3x-10)+32+90=180$

Solving for x, we have:

$\begin{gathered} (3x-10)+32+90=180 \\ 3x-10+32+90=180 \\ 3x=180+10-90-32 \\ 3x=68 \\ x=\frac{68}{3} \\ x=22.67 \end{gathered}$

Therefore, x=22.67 and the answer is A.
