Is it possible to build a triangle with inside angles of 90 degrees , 50 degrees, and 60 degrees?
N76 [4]

Answer:

No

Step-by-step explanation:

Given: Angles of a triangle are equal to 90 degrees , 50 degrees, and 60 degrees

To check : if it possible to build a triangle with given angles

Solution:

According to angle sum property of a triangle, sum of angles of a triangle is equal to 180^{\circ}

Here,

sum of given angles = 90^{\circ}+50^{\circ}+60^{\circ}=200^{\circ}\neq 180^{\circ}

Therefore, it is <u>not possible</u> to construct a triangle with given angles.

How do you do 1/4 (16x+20)-7x
Ira Lisetskai [31]
Distribute the 1/4:
1/4(16x) + 1/4(20) - 7x

Do the multiplication:
1/4(16x) = 16x/4 = 4x
1/4 (20) = 20/4 = 5

Now you have:
4x + 5 - 7x = 0

Combine like terms (4x and -7x):
-3x + 5 = 0

Subtract 5 from both sides:
-3x = -5

Divide by -3:
x = -5/-3 = 5/3

Answer:
x= 5/3
