Question

find the missing values​

Answer 1

Answer:

Step by Step Explanation:

angle(AOB)=angle(COD)

angle(AOB)= 90°

Now,

x+(x-2)+90=180°

2x+88=180°

2x=92

x=46°

Also

4y-1=x

4y=46-1

4y=45

y=11.2

Angles can be measured by putting the values of x and y

Answer 2

In ∆OCD

ANGLE O+ANGLE C+ANGLE D=180°(ANGLE SUM PROPERTY)

90°+3y°+(4y-1)=180

3y+4y-1=90

7y=91

y=91/7

y=13

3y=3*13

=39°

4y-1=4*13-1

52-1

=51°

IN ∆AOB

ANGLE O+ANGLE A+ANGLE B=180°{ANGLE SUM PROPERTY}

90°+X+(X-2)=180°

X+X-2=90

2X=90+2

2X=92

X=46

X-2=46-2

=44
