<span>the correct question is
A triangle whose angles have measures x x+5 and x+10.</span><span>How do you find the measure of each angle?
we know that
The </span><span>Sum of internal angles of any triangle = </span><span>180<span>∘
so
[x+(x+5)+(x+10)]=180---------------> 3x+15=180----------> 3x=165-------> x=55</span></span>°
the answer is
the measure of each angle is
x=55°
x+5=60°
x+10=65°
This is an arithmetic sequence with first term 2 and common difference 7. The general term a[n] can be written as
a[n] = 2 +7(n -1)
or
a[n] = 7n -5
Answer:
The area of triangle expressed as a monomial is 
Step-by-step explanation:
we know that
The area of a triangle is equal to
In this problem we have
substitute
Answer:
The correct answer is -
a. 4.5 inches.
b. side or arm (a)
c. (a) or 4.5, and 18
d. (d) 4.5, and 14.1428
e. 22/7 × r^2 = 15.90
Step-by-step explanation:
Given :
Radius or r = 2 ¼ inches
Solution:
a. the diameter of the circle -
d = 2r
= 2 ¼ *2
= 2.25*2
= 4.5
b. The diameter of the circle is the same length as one side or arm of the square which is
a = d = 4.5
c. The perimeter of the square
P = 4a = 4d = 4*4.5 = 18
d. Perimeter of the circle =
2πr = πd = (22/7)*4.5
= 14.1428
e. the area of the circle =
22/7 × r^2
= 15.90
