Grouping 1 10 as 10 1's is the same because you have just rearranged the numbers but they equal the same
AGB and DGE are acute angles so DGE= 30°. EGF is 100° (50+30+100 {in that order}) (idk the rest
Answer:
b = 7
Step-by-step explanation:
Since the triangle is right use the tangent ratio to solve for b
and the exact value
tan30° = 
, thus
tan30° = 
= 
and
= ( cross- multiply )
b = 7
Answer:
340
Step-by-step explanation:
10 ×16=160
12×15=180
160+180=340 so a total of 340 calendars
Answer:
x = 15
Step-by-step explanation:
The two angles form a straight line so they add to 180 degrees
3+6x + 5x+12 = 180
Combine like terms
11x+15 = 180
Subtract 15 from each side
11x+15-15 =180-15
11x = 165
Divide by 11
11x/11 =165/11
x =15
