Answer:
D. ∠B = ∠B' = 74° and ∠C = ∠C' = 66°
Step-by-step explanation:
Given,
We know,sum of all 3 angles of a triangle is 
°
Doing so ,
Simplifying all like terms,
Dividing both side by 12
Now we plug this in each angles and find their exact values.
°
°
°
Now substituting the in angles of dilated triangle.
°
°
°
We see that all the corresponding angles are equal and as far as the options are concerned only option (D) matches.
D

0.4% can be written as 0.004 in decimal.
Step-by-step explanation:
Let the total amount she wants to save be 'a'
Starting amount = 0.4% of the total amount
= 0.4% of a
= (0.4/100) a
0.4% = 0.4/100
= 0.004
0.4% can be written as 0.004 in decimal.
Ok 1st for the triangles you multiply the base X height then multiply by two. For EX: 5x10=50/2=25 so that's the answer for your first triangle.
