The mathematical property demonstrated by 7+9+3=7+3+9 would be the commutative property. This property states that in operations such as addition and multiplication, when you switch the order of the numbers around, the result will always be the same. In 7+9+3=7+3+9, no matter what order you put the numbers in, the answer will always be 19.

If YU= YV ST=16 mQS=34 and mRT=98 find each measure will mark brainliest
aksik [14]

Answer:

QR=8

QU=76

Measure of arc ST=114°

Measure of arc QR=114°

Measure of arc XT=57°

Step-by-step explanation:

Given

YU=YV

ST=16

mQS=34

mRT=98

Using Pythagoras theorem,

QR=8

QU=76

QR=ST

So they both span the same arc.

Let the arc=x

360 - QS - RT = QR + ST

Recall QR=ST

360 - 34 - 98 = x + x

228 = 2x

X=228/2

X=114°

Therefore, measure of arc ST and arc QR=114° each

Measure of the span of arc XT = (1/2) of (arc ST)

= (1/2)(114°)

= 57°
