HEY GUYS PLS HELP ME WITH THIS GEOMETRY QUESTION

Anuta_ua [19.1K]

Answer:

m∠E = 90°

m∠F = 47°

m∠G = 43°

Step-by-step explanation:

We are given 3 angles: a 90 degree angle, and 2 unknowns. We know that all angles in a triangle add up to 180 degrees. So,

Step 1: Write out the angles equation

90 + 5x - 13 + 2x + 19 = 180

Step 2: Combine like terms

96 + 7x = 180

Step 3: Isolate the x

7x = 84

Step 4: Divide both sides by 7

x = 12

We take this x = 12 and we plug it into our original unknown angles. Thus,

Step 1: ∠F

5(12) - 13

m∠F = 47°

Step 2: ∠G

2(12) + 19

m∠G = 43°

And you have your final answers!

Bao is mixing flour and water to make dough the graph shows how much water he uses for different amounts of flour .How many lite

Allushta [10]

To know how many liters of water Bao use per liter of flour we have to divide the liters or flour so:

$\frac{1}{3}=0.33$

So Bao uses 0.33 or 1/3 of water per liter or flour

and to know hoy manu liters of flour Bao use per liter of water we have to made the oposite division so:

$\frac{3}{1}=3$

She use 3 liters of flour per liter of water

What type of triangle is triangle ABC give reasons for your answer help please I need 1 more mark But I don't know what I'm doin

ladessa [460]

Answer: isosceles

Step-by-step explanation:

By the alternate interior angles theorem, $\angle CAB=50^{\circ}$

Since angles in a triangle add to 180 degrees, $\angle ACB=180^{\circ}-80^{\circ}-50^{\circ}=50^{\circ}$

Since sides opposite equal angles in a triangle are equal, $AB=BC$ .

So, triangle ABC is isosceles
