Answer:

The measure of angle C is 46.

Step-by-step explanation:

In a triangle, all angles add up to 180. So the simple formula for that is:

m∠A + m∠B + m∠C = 180.

Substitute the values given into the equation.

102 + 32 + m∠C = 180

Combine like terms.

134 + m∠C = 180

Subtract 134 from both sides.

m∠C = 46.

Answer:

46

Step-by-step explanation:

180-102+32

180-134

46

All angles of a triangle add up to 180, so you would add up the given angles and subtract them by 180. I hope you found this useful!

Jim, Dan and David share some sweets in the ratio 3:1:5. Jim gets 21 sweets. How many more sweets does David get over Dan?
nadezda [96]

Answer:

David gets 28 more than Dan

Step-by-step explanation:

Jim: Dan : David: total

3   :    1    :  5       : 3+1+5 = 9

Jim gets 21

21/3 = 7

Multiply each number by 7

Jim: Dan : David: total

3*7 :  1*7  :  5 *7  :  9*7

21  :   7     :  35   :  63

David has 35 and Dan has 7

35-7 = 28

David gets 28 more than Dan

Can someone please help me understand how to answer for x, y? Thank you so much!
kodGreya [7K]

Answer:

X = 45°

Y = 72°

Step-by-step explanation:

There is a supplementary angle (an pair of angles that create a straight line is equal to 180°) and there is the rule that all three angles in a triangle equal 180° as well.

How many different triangles can you make with 14cm, 10cm and 50cm sides?
vovangra [49]

Answer:

You can make NO triangles.

When given 3 sides of a triangle, The longest side must be LESS than the sum of the other 2 sides.

Longest Side = 50 cm

50 is NOT less than 14 + 10, therefore, we have no triangle.
