Classify the triangle by its sides and angles

1 answer:

4 0

A right triangle has one 90°angle, and the sum of the 2 other angles equals 90.

an equilateral triangle has all sides and angles of the triangle congruent. each angle will equal 60°

an isosceles triangle has 2 congruent sides and 2 congruent angles.

a scalene triangle has no equal sides or equal angles.

an obtuse triangle has one angle that is greater than 90°

an acute triangle has all angles that are less than 90°

Hope this helps you classify your triangles!

Gerry plans to place a 29 foot ladder against the side of his house to clean his gutters. The bottom of the ladder will be 3 fee

tensa zangetsu [6.8K]

Answer:

8 $\sqrt{13}$

Step-by-step explanation:

Using the pythagorean theorem (Assuming the house's walls are perpindicular to the ground):

a^2+b^2=c^2

we can find that 3=a and 29=c

3^2+b^2=29^2

9+b^2=841

b^2=832

b= $\sqrt{832}$

b= $\sqrt{64*13}$

b=8 $\sqrt{13}$

That is the height that the ladder will reach

The owner of a convenience store keeps track of how many customer buy lunch food during the "noon rush" each day for four days a

alexdok [17]

Answer:

c) 62.

Step-by-step explanation:

Let x represent number of customers came in on the fifth day.

We have been given that the mean number of customers for those four days is 52. So total number of customers on 4 days would be 4 times 52 that is 208 customers.

We know that mean of a data set is equal to sum of all data points divided by number of data points.

Total number of customers on 5 days would be $208+x$ and total number of days is 5.
