Solve the equation simultaneously ax + by + c = 0 px + qy + r = 0I will mark as brainliest. please tell​

Answer»

ong>Step-by-step EXPLANATION:

ax+by = -c ..(1)

px + QY = -R ..(2)

then (1)*p - (2)*p ;

apx + bpy = -cp

apx + aqy = -ra

y = (ra-cp)/(bp-aq)

ax = -c - (abr - CBP) /(bp-aq)

Adjacent angles of parallelogramare of measure 2x & 7x then find thevalue of 'x'.​

Answer»

ong>Answer:

20 degrees

Step-by-step explanation:

Adjacent angles of a PARALLELOGRAM are supplementary SINCE the OPPOSITE SIDES are parallel.

Therefore,

2x + 7x = 180°

9x = 180°

x = 20°

33. Two angles forming a linear pair are in the ratio of 3:7. Find the two angles.​

Answer»

Solution:-

━━━━━━━━━━━━━━━━━━━━━━━━━━

\large\to{\underbrace{\underline{\sf{Understanding\:the\:concept:-}}}}

\implies Here in the question we are given that two angles forming a LINEAR pair are in the ratio of 3:7. Now, the question has asked us to find out those 2 angles. So, to find the angles follow the steps shown below.

ANSWER:-

1ST angle = 54°

⬤ 2nd angle = 126°

GIVEN:-

⟼ 1st angle = 3x

⟼ 2nd angle = 7x

TO FIND:-

⟿ 1st angle = ?

⟿ 2nd angle = ?

ALGORITHM USED:-

➜ Linear pair:- Angles formed when two lines intersect. Their sum is equal to 180°.

➜ Supplementary angle:- The sum of two angles = 180°

➜ Linear pair can SAID to be supplementary.

➜ So, In the question we used linear pair axiom i.e, the sum of given angles will be equal to 180°

Considering the angle 1 be 3x and angle 2 be 7x respectively.

SOLVING BY APPLYING THE FORMULA:-

⟼ 1st angle = 3x

⟼ 2nd angle = 7x

  • Finding the angles:-

We know that the sum of a linear pair is 180°.

So,

➜ 3x + 7x = 180°

Adding the terms:- 3x + 7x = 10x

So,

➜ 10x = 180°

Taking 10 to R.H.S.

So,

➜ x = 180° / 10

Remainder after dividing 180° / 10 is 18°.

So,

➜ x = 18°

  • Angles:-

➜ 1st angle = 3x

3x = 3 × 18

= 54°

Angle 1 = 54°

➜ 2nd angle = 7x

7x = 7 × 18

= 126°

Angle 2 = 126°.

VERIFICATION:-

➜ 54° + 126°

➜ 54° + 126° = 180°

➜ 180°

L.H.S = R.H.S

Hence, verifed.

PQ and PR are the two tangent of the circle with centre O. If the length of QR is 8 cm and the radius of the circle(i.e. QO) is 5 cm. Find the value of QP.WITH STEP BY STEP EXPLANATION.... PLAEASE ASAP....NEED URGENTLY​

Answer» ONG>ANSWER:

Lengths of the tangents DRAWN from an EXTERNAL point to a circle are equal.

∴QP=PT=3.8cm

PR=PT=3.8cm

From equations (i) and (ii)

QP=PR=3.8cm

But, QR=QP+PR

∴QR=3.8+3.8

QR=7.6cm

Step-by-step explanation:

Lengths of the tangents drawn from an external point to a circle are equal.

∴QP=PT=3.8cm

PR=PT=3.8cm

From equations (i) and (ii):

QP=PR=3.8cm

But, QR=QP+PR

∴QR=3.8+3.8

QR=7.6cm

In the given figure, if1 = 30°, find 2 and 3.​

Answer»

ong>ANSWER:

/_ 1 = 30° ----(given)

therefore, /_1 + /_2 = 180° ----(linear PAIR)

, 30° + /_2 = 180°

, /_2 = 180° — 30°

, /_2 = 150°

& also

/_1 = /_3 = 30°---(virtically opposite angles)

therefore,

/_3 = 30°
