The leg of a right triangle is 3 units and the hypotenuse is 7 units. What is the length, in units, of the other leg of the tria

sweet-ann [11.9K]

A^2 + b^2 = c^2....where a and b are the legs, c is the hypotenuse
3^2 + b^2 = 7^2
9 + b^2 = 49
b^2 = 49 - 9
b^2 = 40.....take sqrt of both sides, eliminating the ^2
b = square root of 40 <==

Can i get help with these 6 questions

Andreyy89

Answer:

Question 21

∠PQS = 22°
∠PQR = 44°

Question 22

∠ABC = 47°
∠CBD = 47°

Question 23

∠ABD = 35°
∠DBC = 35°
∠ABC = 70°

Step-by-step explanation:

When the question says a line bisects an angle which means that this line is cut exactly at the centre of an angle so both angles will be the same :

Question 21,

$∠PQR = ∠SQR$

$∠PQS = 22°$

$∠PQR = ∠PQS + ∠SQR$

$∠PQR = 22 + 22 = 44°$

Question 22,

$∠ABD = 94°$

$∠ABC = ∠CBD = 94 \div 2 = 47°$

Question 23,

$∠ABD = ∠DBC$

$x + 15 = 4x - 45$

$4x - x = 15 + 45$

$3x = 60$

$x = 60 ÷ 3 = 20°$

$∠ABD = 20 + 15 = 35°$

$∠DBC = 4(20) - 45 = 35°$

$∠ABC = ∠ABD + ∠DBC = 35 + 35 = 70°$

Pachacha [2.7K]

Answer:

140%

If it is 40% more than last year, it is 40% more than 100%. You add 100 and 40 and get 140%.
