Answer:
Triangles 3 and 4 are both isosceles. They each have a 60 degree angle.
This is a similar triangle.
Step-by-step explanation:
Isosceles triangle is one in which two sides are equal.
Similar triangles are triangles which have all corresponding angles equal and which have corresponding sides with the same ratio.
Now the given isosceles triangle both have all three angles equal to 60 degrees which makes them similar triangles.
The other choices given are not similar triangles because
1) they do not have all corresponding angles equal
2) their lengths are unknown and cannot be assumed to be in ratio.
Answer:
28.8
Step-by-step explanation:
23+2x+3x+13=180 simplify the left side
5x+36=180 subtract 36 from both sides
5x=144 divide both sides by 5 to isolate the variable
x=28.8
Answer:
∠DCE is congruent to ∠CBA by the Vertical Angles Theorem and 15 over 5 equals 12 over 4 shows the corresponding sides are proportional; therefore, ΔABC ~ ΔEDC by the SSS Similarity Postulate.
Step-by-step explanation:
Answer:
length = 16 feet
width = 12 feet
Step-by-step explanation:
divide the length and width by 2 so you get 3 and 4. then you proceed to Multiply both by 4 and you get 12 and 16
6÷2 = 3
8÷2 = 4
3x4= 12
4x4 = 16
In this question the answer is x is equal to exactly 1.749... Or 1.75
