QRST is a square. PQ = 2√ RU = 4 What is the length of SU? Round to the nearest tenth.

777dan777 [17]

Answer:

$SU=3.5\ units$

Step-by-step explanation:

step 1

In the isosceles right triangle PQT

PQ=PT ----> because is an isosceles triangle

Applying the Pythagoras Theorem

we have

$PQ=PT =\sqrt{2}\ units$

$QT^{2}=PQ^{2} +PT^{2}$

substitute the values

$QT^{2}=\sqrt{2}^{2} +\sqrt{2}^{2}$

$QT^{2}=4$

$QT=2\ units$

step 2

In the square QRST

$RS=QT=2\ units$

step 3

In the right triangle RSU

Applying the Pythagoras Theorem

$RU^{2}=RS^{2} +SU^{2}$

we have

$RU=4\ units$

$RS=2\ units$

substitute the values and solve for SU

$4^{2}=2^{2} +SU^{2}$

$SU^{2}=4^{2}-2^{2}$

$SU^{2}=12$

$SU=2\sqrt{3}\ units$

$SU=3.5\ units$

Aiden brought chocolate and vanilla cupcakes to school for his birthday. 12 students picked a vanilla cupcake and 88 students pi

White raven [17]

Answer:

the percentage is 12%

Step-by-step explanation:

Given that

The 12 students picked up the vanilla cupcake

And, 88 students picked up the chocolate cupcake

We need to find out the percentage of the students picked up a vanilla cupcake

So, the percenatge is

= (12) ÷ (12 + 88) × 100

= 12 ÷ 100 × 100

= 12%

Hence, the percentage is 12%

Answer quickly only if you know

Neko [114]

The figure has 5 sides, so it must be a pentagon. Pentagon’s interior angles sum up to 540°.

Therefore:

132+90+3x=540

222+3x=540

3x=318

x=106

Checking work, where x=106

222+3(106)=540.

So x°=106°
