1) Triangles are not similar, for triangles to be similar their sides have to be proportional which doesn't happen in this case
2)Triangles are Similar(ΔCBA ~ ΔFGH) all their sides are proportional meeting the SSS theorem that all sides have to be proportional making the two triangles similar
3)Triangles are Similar(ΔVUT ~ ΔVLM), two sides of each given triangle are proportional to each other and by the vertical angle theorem, ∠MVL is equal to ∠TVU. Thus it meets the SSA theorem which states the two sides of each given triangle must proportional and one angle of each triangle are equal.
4)Triangles are Similar(ΔJKL ~ΔTUV), because two angles of each triangle are equal, it meets that AA theorem that if two given angles of each triangle are equal, then the triangles are similar.
5) Triangles are not similar, only one angle of each triangle is equal and thus the two triangles are not similar
6) Triangles are not similar, the sides are not proportional to each other with the same ratio, so the triangles are not similar
Hope that helps!
if you don't have a Unit Circle yet, this is a good time to get one, you can find many online, check maybe in yahoo images, or google images.
Check the picture below.
notice the section encircled in purple.
AREA OF A SECTOR =1/2(Ф.R²). Note that R = Diameter/2
AREA OF A SECTOR =1/2(170°).(9.1)/2) =386.75 cm²
Answer: (17.310 would round up to 18) (7.14 would round down to just 17) So your new equation will be 18 + 17 =35
Step-by-step explanation:
Answer:
x = 1/2
Step-by-step explanation:
4x-3 + 5 = 2x + 7 - 8x
Combine like terms
4x +2 = 7-6x
Add 6x to each side
4x+2+6x = 7-6x+6x
10x+2 = 7
Subtract 2 from each side
10x+2-2 = 7-2
10x = 5
Divide by 10
10x/10 = 5/10
x = 1/2
