ABCD is a rectangle. Its diagonals meet at O. Find the value of x if BO = 3x + 4 andOC = x + 8 .Also find the length of its diag

scoundrel [369]

Step-by-step explanation:

the lengths OB, OC & BC together forms a isosceles triangle.

therefore,

OB=OC

3x+4=x+8

2x=4

x=2.

OB = 3x+4= 3.2+4=10cm.

OC= x+8= 2+8=10cm.

therefore, the diagonals are : 20cm each.

hope this helps you.

Maria calls her mother 5 times every week. Let w represent the number of weeks and c represent the total number of times Maria c

galina1969 [7]

Answer:

Equation: 5w = c

Step-by-step explanation:

${ \tt{w \: \alpha \: c}} \\ { \tt{w = kc}}$

k is a constant of proprtionality

${ \tt{1 = (k \times 5)}} \\ { \tt{k = \frac{1}{5} }}$

» Therefore, equation becomes:

${ \tt{w = \frac{1}{5}c }} \\ \\ { \boxed{ \tt{5w = c}}}$

3÷ 1/4. 7÷ 1/2. 1/5÷ 1/20. 1/2÷ 1/10. 1/7÷ 3.. help me solve all these please.

Nina [5.8K]

Answer:

Step-by-step explanation:

Use KCF method for fraction division.

Keep the first fraction

Change the operation to multiplication

Flip the second fraction.

1) 3÷ (1/4) = $3*\frac{4}{1}= 12$

2) 7 ÷ (1/2) = $7 * \frac{2}{1}=14$

3) (1/5) ÷ (1/20) = $\frac{1}{5}*\frac{20}{1}=4$

4) (1/2) ÷ (1/10) = $\frac{1}{2}*\frac{10}{1}=5$

5) (1/7) ÷ 3 = $\frac{1}{7}*\frac{1}{3}=\frac{1}{21}$

Circle T is shown. Line PS and line RS are tangent to circle T. What is the measure, in degrees, of angle PTR

Paladinen [302]

0Answer:

Angle PTR is 136*

Step-by-step explanation:

In Question, We Have Given

Line PS and RS are Two Tangent To Circle With Centre T & ∠PSR=44* .

Thus ∠SPT=90* & ∠SRT=90* (Property Of Tangent ↔ Tangent always Form 90* With Radius Of Circle)

Now We Have A Quadrilateral SPTR & The Sum Of All Angle Of Quadrilateral is 360* .

Thus The Angle Of PTR is

∠PTR = 360* - ( 90*+90*+44*)

∠PTR = 360* - 224*

∠PTR = 136*
