<h2>sum of a triangle= 180°</h2>
- 63+56=119
- 180-119=61
- ans=61°
1.5(x + 4) - 3 = 3.5(x - 2)
We need to use the distributive property to simplify this.
1.5x + 6 - 3 = 3.5x - 7
<em><u>Subtract 1.5x from both sides</u></em>
6 - 3 = 2x - 7
<em><u>Simplify left side</u></em>
3 = 2x - 7
<em><u>Add 7 to both sides</u></em>
10 = 2x
<em><u>Divide both sides by 2</u></em>
x = 5
Answer:
d.10cm,5cm,9cm
Step-by-step explanation:
In a triangle, the length of each side must be between the difference and the sum of the lengths of the other sides.
a. 1 + 1 = 2; 2 < 3 Answer: no
b. 2 + 3 = 5; 5 = 5 Answer: no
c. 10 - 3 = 7; 7 > 4 Answer: no
d. 10 + 5 > 9
5 + 9 > 10
10 + 9 > 5
10 - 5 < 9
10 - 9 < 5
9 - 5 <10
Answer: yes
Answer:
No, triangles CDE and HGF are not necessarily congruent.
Step-by-step explanation:
Notice that just having one angle equal in value doesn't make the triangles congruent. To start with, we know that the three internal angles of a triangle must add up to 180 degrees, but all we know when one is 50 degrees, the other two must add up to 130 degrees, which can be done by an infinite number of different angle combinations: 110 + 20, 90 + 40, 80 + 50, etc.
