Answer:

HL, SSS, SAS  can be used to prove both triangles congruent.

Step-by-step explanation:

In ΔABR And ΔACR we are given following corresponding equal parts,

∠B = ∠C = 90°

AB = AC

BR = CR

AR = AR (common)

1st. ΔABR ≅ ΔACR By HL congruence rule

as Hypotenuse AR = AR & 1 leg AB = AC or BR = CR

2nd ΔABR ≅ ΔACR By SSS congruence rule

as AB = AC & BR = CR & AR = AR (All sides of ΔABR equals to sides of ΔACR)

3rd ΔABR ≅ ΔACR By SAS congruence rule

AB = AC & ∠B = ∠C & BR = CR (2 sides of ΔABR equals to 2 sides of ΔACR and angle between both side are also equal)

ΔABR and ΔACR can not be congruent by ASA & AAS rule because no 2nd equal angle is not given.

HL (It's a right triangle and the hypotenuse and leg are congruent. This can also be thought of as SAS.)

SAS (Side angle side. All congruent.)

SSS (Line AR is shared by both triangles. A line is always congruent on itself. The other two are self explanatory.)

ASA and AAS cannot be used because we can only confidently confirm one angle of each triangle.

Find the value of the variable and BC, if B is between A and C.<br> AB = 5x, BC = 3x-1, AC = 47
schepotkina [342]

Answer:

17

Step-by-step explanation:

AC = AB + BC

Since we know what each variable equals, we can write out the equation as shown:

47 = 5x + 3x - 1

Combining like terms:

47 = 8x - 1

Add 1 on both sides:

48 = 8x

Divide 8 on both sides:

X = 6

Now that we know what X equals, we can solve BC.

BC = 3(6) - 1

BC = 18 - 1

BC = 17

Therefore BC = 17.

Solve each equation. Check 19. x(x - 32)=0​
Readme [11.4K]

Answer:

x is equal to thirty-two.

Step-by-step explanation:

x(x - 32) = 0

x² - 32x = 0

x - 32 = 0

x = 32

Sue has 20 biscuits in a tin There are 12 plain biscuits 5 chocolate biscuits 3 currant biscuits Sue takes at 2 random biscuits
vagabundo [1.1K]

Answer:

111 / 190

Step-by-step explanation:

Total biscuits = 20

Plain, P = 12

Chocolate, C = 5

Currant, K = 3

Assume without replacement :

Probability that biscuit are of the same type :

P(plain) :

12 / 20 * 11 / 19 = 132 / 380

P(chocolate) :

5/ 20 * 4 / 19 = 20/ 380

P(currant) :

3/20 * 2 /19 = 6 / 380

Therefore,

Probability that biscuit is of the same type :

P(plain) + P(chocolate) + P(currant)

132/380 + 20/380 + 6/380

158 / 380 = 79 / 190

Therefore, probability that biscuit aren't of the same type :

1 - P(biscuit is of same type)

1 - 79/190

(190 - 79) / 190

111 / 190
