Answer:
x = 17 and y = 10
Step-by-step explanation:
ABCD is a parallelogram
So AB = CD and AD = BC
so
3x - 9 = 42
3x = 51
x = 17
and
4y - 3 = 37
4y = 40
y = 10
Answer
x = 17 and y = 10
Answer:
A) False - not a right angle
B) True - it is a right angle
C) True - it is a right angle
D) False-not a right angle
Step-by-step explanation:
A) a*a+b*b=c*c (Asquared+Bsquared=C squared)
2*2+ 3*3 = 4*4
4+9=16
13 does not equal 16
B) 5*5+12*12=13+13
25+144=169
169=169 - True
C) 3*3+4*4=5*5
9+16=25
25=25 (True)
D) 4+ Root of 3 = Root of 19
False - square root of a prime number is irrational
Circumference of circle = π × Diameter
= π × 18 cm
= 56.54867 or 56.54 to 1 dp
Answer:
1. x= y/5 + 22/5
2. y=17 − 3x2
Step-by-step explanation:
for 2 and so on
Step-by-step explanation:
for number 2= measure the angle with the protractor and thats the answer
for number 3= A
for number 4= add 41 and 82 then do 180- that number
