Answer:
9cm
Step-by-step explanation:
- Since PQST is a rectangle, ∠QST=∠QSR=∠90º. So triangle QSR is a right triangle.
- By the Pythagorean Theorem and that SR=6 and QR=10, we can say that 6^2+b^2=10^2. So, 36+b^2=100. And b^2=64 and b=8. So QS=8.
- Now we know that QS=PT=8.
- By the Pythagorean Theorem and that PR=17 and PT=8, we can say a^2+8^2=17^2. So, a^2+64=289. And a^2=225 and a=15.
- We know that TR=15 and SR=6 and TR-SR=TS, so 15-6=9.
84 cm because you HAVE to add them together.
Answer:
Step-by-step explanation:
If two chords intersect inside a circle, then
DE * BE =AE * CE
10*x = 8*6
10x = 48
x = 48/10
x = 4.8
Answer:
#2) is 25
Step-by-step explanation:
the best way to solve any of theses is in the order of pemdas:
●parentheses
●exponents
●multiplication & division
●addition & subtraction
for example lets do #2
9+ (2^2)(4)
the first parenthesis has exponents so you'd do it first. 2^2 (two two times) is 4
9+(4)(4)
when two parentheses are next to Each other you multiply. 4x4 is 16
9+16
then finally you add
25
use these steps for the rest. just comment if you have any questions
MUSTARD MAN
1) 16y+0=0 Identity Property Of Addition
2) d*r=r*d Commutive property of multiplication
3) 27a*0=0 Identity Property of Addition
4) 16x+5y=5y+16x Commutive property of Addition
5) r*1=r Identity property of Addition
6) (5y+2)+14x=5y+(2+14x) Associate property of Addition
7) (m*n)*p=m*(n*p) Associate Property of Multiplication
Please use the information you have to make sure these are RIGHT!!!!
